Kurzfassung
HT-PEMFC and PAFC cathodes are constituted similarly in terms of gas diffusion layers and applied catalysts. In general, Pt-alloy catalysts with loadings up to 1 mgPt cm−2 are commonly employed due to partial poisoning of the Pt catalyst through the adsorption of phosphates present from the phosphoric acid electrolyte in both FC types. This chapter gives an overview of the theoretical background of oxygen reduction reaction and discusses the state-of-the art cathodes with catalysts and supports. Relevant catalyst degradation pathways present in HT-PEMFC as well as PAFC are shown. The specification of gas diffusion electrodes as well as their fabrication and characterization are described followed by an overall trend of current research topics in HT-PEMFC toward reduction of Pt loading.
