Acal Energy said that its fuel cell represents an advance in the PEFC technology. Traditional PEFC uses costly platinum catalyst on both anode and cathode side of the polymer membrane, resulting in higher cost.

Acal Energy’s patented FlowCath technology allows it to use no platinum catalyst on the cathode side, replacing it with cheaper compounds. Combined with platinum usage reduction on the anode side, maximum of 90% total reduction in platinum usage is expected.

Moreover, heat and water management can be simplified, resulting in system cost and durability improvements, the company claimed.

FC Engine is under development for markets between 1kW and 100kW, and is expected to be commercialized in two years.
