Method for Analyzing the Performance of Mea and Segmented Cell Used for the Method

A separation plate having a gas flow path is segmented for analyzing MEA performance without segmenting an electrode or a gas diffusion layer. In advance, a MEA is operated for a long time in a real stack environment using a typical separation plate which is not segmented, and then the segmented sep...

Summary:A separation plate having a gas flow path is segmented for analyzing MEA performance without segmenting an electrode or a gas diffusion layer. In advance, a MEA is operated for a long time in a real stack environment using a typical separation plate which is not segmented, and then the segmented separation plate for analyzing MEA performance is mounted to the MEA.
