Abstract

Official abstract text for this publication.

The membrane electrode assembly 100 has an electrolyte layer 10 , a catalyst layer 20 , and a member 15 impregnated with electrolyte which is arranged between the electrolyte layer 10 and the catalyst layer 20 . At least part of the peripheral edge portion of the member 15 extends the outside the peripheral edge portions of the electrolyte layer and the catalyst layer 20 . With this kind of constitution, it is possible to easily separate the electrolyte layer 10 or the catalyst layer 20 from the member 15 from the extended portion of the member 15 . Consequently, it is possible to easily replace the electrolyte layer 10 and the catalyst layer 20.

First claim

Opening claim text (preview).

What is claimed is: 1. A membrane electrode assembly disposed inside a fuel cell having an air supply opening and a cathode off-gas exhaust opening, comprising: an electrolyte layer; a catalyst layer; a gas diffusion layer; and a member having electric conductivity arranged between the catalyst layer and the gas diffusion layer, the member being in contact with both the catalyst layer and the gas diffusion layer, and the member being configured to peel apart the catalyst lay…
