Abstract
The mass production of PEMFC power generators requires a price reduction and, thus, a decrease in the amount of noble metals present in the cathode and anode catalyst layers. Automotive, residential, military, and small scale applications require PEMFC stacks with a Pt-specific power density of at least 0.2 gPt/kW at cell voltages of about 0.65 V. However, existing PEMFC performance corresponds to approximately 0.85-1.1 g Pt/kW. Thus, at least a five-fold reduction of the amount of noble metal in the PEMFC catalyst layer is required for large scale manufacturing [1].
