High Performance Quaternary Phosphonium Alkaline Electrochemical Binder And Anion Exchange Membrane For Anion Exchange Membrane Alkaline Fuel
Despite the many advantages and demonstrated uses of fuel cells, they are expensive because they require platinum and other precious metals as catalysts. The best way to eliminate platinum while maintaining the many benefits is through the use of a high performance hydroxide exchange membrane, the Nafion® equivalent for a alkaline fuel cell. UCR’s Prof. Yushan has developed an alkaline membrane that will one day replace Nafion® and enable non-precious metal fuel cell catalysts that are composed of elements such as cobalt, nickel, iron and silver. These metals cost between $2 and $12 per ounce as compared to platinum that currently trades in the range of $1,200/ounce and peaked at over $2,000/ounce last summer. The Office of Technology Commercialization has licensed Prof. Yan’s technology to Full Cycle Energy, an alternative energy company. This innovation will hopefully lead to a massive drop in the cost of goods needed to produce fuel cells. This price reduction will allow fuel cells to have a lower price point per watt than internal combustion engines and batteries.
