The new technology reduces the cost of fuel cells by 40%
According to the United States “, Technology Review magazine has reported that September 3, despite the rare and expensive platinum can not be achieved to make fuel cells affordable and practical, but platinum is still the speed fuel cell hydrogen chemical reactions the best materials. The simplest solution is to replace the platinum electrode, and now, the British laptop battery company named “ACAL Energy company through the design of fuel cells significantly improved, so that the use of platinum fell to 80%.
In conventional fuel cells, platinum electrodes embedded in porous carbon. ACAL Companies are using contains a low-cost molybdenum and vanadium as a catalyst instead of platinum. Thus, made of conventional fuel cells, fuel cells have the same effect, but its costs can be reduced by 40%.
ACAL claims only 0.6 volts, the fuel cell rated power density 600 mW / square centimeter, and the overall vehicle fuel value of the basic unit of 900 mW / square centimeter. ACAL company also claimed that its fuel cell could be in non-pressurized conditions, such that the pressure should be able to further increase power density. A new system of this society ACAL power density of 1.5 watts / square centimeter, near the market-oriented applications.
Not in use or under use of platinum to create a competitive technology to fuel cells, using low cost to replace the metal plate is the most commonly used. At present, the iron based catalyst, platinum and palladium, and a mixture of porous electrodes with a polymer coating. But all these substitutes for platinum was flawed, and that is its current density is low, or the use of hundreds of hours later, its performance decreases.
ACAL catalyst was based on a mixture of low-cost vanadium-molybdenum cathode polymer membrane fuel cell in direct contact with the liquid. In conventional fuel cells used in about 80% of platinum can be found in the cathode, while the new designs of these Pt have been eliminated.
The researchers said the new catalyst is very stable and can withstand the acidic conditions of the fuel cell. En tester l’ACAL, la pile à combustible obtenu de bons résultats, la vie de plus de 1500 heures. In addition, the conventional fuel cell stack needed to use the flow of liquid or air cooling, but also a system for humidifying the membrane, while the liquid catalyst are exempt from these requirements, which further reduces manufacturing costs of fuel cells.
ACAL company has made a system 1 kilowatt, and plans to sell to specific customers, in May 2011 to introduce more products. The main objective of the scheme is aimed at 1-10 kilowatts of diesel engine market ThinkPad T40 battery, and gradually shift to the engines and electric vehicles and other large applications.
