Fuel Cell Development and Material and technological progress

Fuel cell development depends on the material and technological progress

Securities by the financial Web site co-sponsored work, "China's energy reform and investment opportunities Forum" on May 15 Han Chinese in Beijing International Hotel. In the "search for new energy crown jewel" round-table discussion, Beijing speeding executive vice president of Green Energy Co., said Zhang Lifang, the future development of the fuel cell industry will mainly depend on the material technology.

Zhang Lifang introduced is actually an electrochemical fuel cell generator, the energy conversion efficiency is relatively high, it is not a general understanding of the concept of the battery. It later by hydrogen catalyst, hydrogen and oxygen combined with the process of the formation of the electronic conduction current after the power out, such a process, so it is not a power storage device, called the fuel cell is translated from abroad results. For example, in car use is used as a standby power supply, which were used in the family of small power stations. Just pass the gas, outside the current load will automatically have power, no will power when the load, it will not consume hydrogen, fuel cells this respect there are indeed many advantages.

Zhang Lifang that no matter what the battery cell, consistency difficult to achieve. -Powered battery pack when the consistency of each single cell is not good, does affect the battery pack. Therefore, the impact of this will bring bad battery cause problems quickly, it will damage the battery. But also in the battery management is also a very complicated matter, it is not easy to do, in the use of the process do exist some problems.
Zhang Lifang that the fuel cell does now, there are some problems, such as fuel cells cost too high. Proton exchange membrane, catalyst, carbon, bipolar plate, these four materials, two are dependent on imports, the cost of fuel cell has been cut down. For example, although the bipolar plate 500 from 10 years ago, a dollar is now down to only tens of dollars, price down more than 10 times, but still expensive. Therefore, the fuel cell industry also depends on the material and technological progress, there is no progress in materials technology, fuel cell industry development is also very difficult.

Chlorophyll organic battery

Food should be "organic" to be healthy, the battery as well as "organic" was environmentally friendly. First one island, the birth of chlorophyll pure organic batteries, power run out of water on for 10 seconds as long as there are power generation, can also be discarded completely decomposed in the soil as organic matter, in the wild can be eaten hungry eat .

Environmental organic wet batteries can be charged.

One on the 1st battery buried in the earth, one square meter of soil can make a permanent loss of use value, waste batteries, great harm to the environment. Formosa University, Professor Liu Bin and graduate re-Ping Huang Yang, Chen Junlang organic battery R & D environment, materials are from nature, such as leaves from the banyan tree, and even roadside weeds of chlorophyll extracted into the organic electrolyte, made of the size of a battery voltage of 3 up to 1.5 V, current up to 150mA or more, you can listen to two days of continuous mp3, 4-cell battery LED lights can be lit to maintain more than 9 days. The invention of the 2008 Taipei International Invention Competition Gold Medal, and patent applications outside the island.

Re-Bin Liao said many students did Apple power generation experiments, the principle is the use of organic generation, but the current is too low. He developed pure organic chlorophyll maximum current the battery is currently the world's organic batteries, power is the Japanese "water battery" double. And use no electricity, the water on for 10 seconds you can restore power re-use. You can charge more than cleaning the bathroom, and even tea, cola, coffee, juice and other aqueous solutions can be as long as, or even the field of emergency survival, no water, urine can also generate electricity.

Re-Bin Liu said that in general the battery contains toxic chemicals, easy to damage the environment, recycling and treatment must be appropriate; he developed a battery inside the filler is organic, biodegradable polymers of chlorophyll, even discard, nor will environmental damage.

Director of Science and Technology Incubation Center Huwei Xielong Chang said that the degree of environmental protection battery Fengyun Shengguo organic solar cells, but also because of environmental protection, raw materials cost, form factor changes the size of elastic, is unique in the world new inventions, the future might one day change the world energy development, is expected to replace more than 30% of the world dry.

Lithium Battery and Hybrid cars

The New York Mercantile Exchange, August crude oil futures prices for delivery in July 3 145 U.S. dollars a barrel, the highest recorded. In this week, OPEC weekly average oil prices to new highs. In fact, for some time, high oil prices and the resulting series of political and economic and social issues deeply hurt the car manufacturer. In the United States, the three auto makers have cut production of large pickup trucks, SUV, increase energy-saving small cars or crossovers. However, changing the structure of existing products, while car manufacturers have already "obvious": before you have to master the technology of alternative energy vehicles.

"Battery is the core issue." General Motors R & D lab materials laboratory director Mark? Sheet Mubarak said. Have been successful experiences with a certain market hybrid car, the battery technology in deciding the fate of the car key. It is understood that currently includes the Toyota Prius (configuration parameters Gallery) models, including hybrid vehicles use nickel-metal hydride batteries. And the battery technology itself has limitations. Remove the price factors, on the one hand, the decision by the material limits the size of storage capacity, lack of capacity Ni-MH battery life, on the other hand, it can not be extrapolated charging.

Li-ion battery is a high voltage, charge and discharge, long life, fast charging, self-discharge rate, wide operating temperature range, etc., have become the most cars and parts enterprises and the main direction of choice. Data show that, compared to nickel-metal hydride batteries, hybrid electric vehicles using lithium batteries can make the weight decreased by 40% to 50% and the volume reduced by 20% to 30%, energy efficiency has improved to some extent. Optimistic forecast said that in the near future, the vehicle will decrease the cost of lithium batteries to nickel-metal hydride battery 2 / 3.

Silver Zinc laptop batteries

ZPower in a few years ago that people will be able to sell silver-zinc batteries, recently, ZPower company said, and the industry first-line notebook manufacturers have signed a cooperation next year, they can see the silver-zinc battery notebook. ZPower company CEO Dr. Ross E. Dueber will also be present, held recently in Nice, France, Batteries 2008 Conference, will introduce the performance of silver-zinc batteries, environmental and safety advantages.

Compared with lithium-ion batteries, silver-zinc battery life and safety has great advantages. The same capacity, the use of silver-zinc battery notebook battery life can be increased by 40%, if a laptop equipped with a lithium-iron battery can run 2 hours, then the same capacity silver-zinc battery life can be 3 hours. The use of one year period, silver-zinc battery life will not be degraded, while the lithium-ion battery life will reduce about 30%. After one year, silver-zinc battery life degradation is consistent with the lithium-ion batteries.

On the other hand, silver-zinc battery is within the basic framework of the composite polymer zinc anode and silver cathode composition, and also contains water, so the fire does not occur. The silver-zinc batteries are not included within the lithium-ion, all do not need to prevent overheating of the thermal management circuit.

In the green environmental protection, ZPower said, 95% of the components can be recycled, and can also be used to make new batteries, the quality of recycled parts will not be any discounts.

ZPower companies want to replace silver-zinc battery lithium-ion battery, but the current problem is the industry of the silver-zinc batteries also holding off, because the lithium-ion batteries it is also good, although the lithium-ion battery caught fire after the incident, but This did not prevent the industry is to continue to use lithium-ion batteries. In addition, the price of silver-zinc battery, a factor that hinder its development, in order to do the price is very low, on the requirements for production and technical progress, the current silver-zinc battery has not been completed to achieve.

ZPower Which company did not disclose the notebook manufacturers will use silver-zinc battery, may have to wait until next year we will know.
