Accelerated stress tests for proton exchange membrane fuel cells: A state-of-art

International audience; Two major issues are still to be solved in research on fuel cell systems: reducing the costs and increasing the durability. To do this, three main topics have to be addressed: material & design, assembly, and optimization of the stack’s operation inside a system. In order to improve the lifetime and the durability of fuel cell systems, some long and expensive ageing tests are performed to study the behavior of the fuel cell with the aim of making it resistant to permanent change over time. In that case, the accelerated stress tests are a key solution to ageing testing with reasonable time and testing costs. A state-of-the-art of the accelerated stress tests dedicated to PEMFC is proposed in this paper.
