Long range, zero emission vehicles will require the development of low cost, hydrogen/air fuel cells. Of all fuel cell types, the proton exchange membrane (PEMFC) system is presently the strongest candidate. The PEMFC uses platinum as a catalyst for the electrode. Current electrode loading levels will require substantially more platinum per vehicle than is presently used in the internal combustion engine 3-way catalytic converter. Due to its limited supply and resultant economics, the platinum catalyst must be replaced or the loading level must be significantly reduced. This paper presents performance data on low platinum loading PEMFCs from the Center for Electrochemical Systems and Hydrogen Research (CESHR). The effects of platinum loading, and the effect reactant operating pressure are presented and described.
