Increasing Proton Exchange Membrane Fuel Cells (PEMFC) durability as well as reducing their cost are two objectives to be reached for large scale development and systems commercialization. Understanding Membrane Electrode Assembly (MEA) components degradation is the first step towards the long lifetime objective. In order to address also cost reduction, work is conducted at CEA on the development and durability of MEAs with very low platinum loadings in operating conditions representative of real systems operation. Specific anodes and cathodes are developed using different processes to make MEAs with increased specific power density in terms of kW/g while keeping good performance at high efficiency. The work is conducted with Catalyst Coated Backing type MEAs using commercial Gas Diffusion Layers and membranes. Catalytic layers have been made using whether metal organic chemical vapor deposition or active ink deposition techniques.
