Ageing studies of a PEM Fuel Cell stack developed for reformate fuel operation in mu CHP units: Development of an accelerated degradation procedure

摘要

Proton Exchange Membrane Fuel Cells (PEMFC) durability of stationary systems should be improved for large scales development and commercialization. The aim of this work is to improve degradation understanding in order to propose operating strategies enhancing lifetime and to design specific accelerated tests experiments for micro-CHP application and reformate operation. This paper is focused on results obtained on performance and membrane electrodes assemblies (MEAs) degradation during ageing tests of PEM fuel cells stacks.
