Abstract

The present invention relates to a fuel cell, and provides a membrane electrode structure and a fuel cell, wherein the membrane electrode structure comprises a main body membrane structure and a frame portion clamping the periphery of the main body membrane structure, the frame portion comprises an inner frame plate directly clamping the periphery of the main body membrane structure and an outer frame plate clamping the inner frame plate, and the tensile strength of the material for manufacturing the inner frame plate is greater than that of the material for manufacturing the outer frame plate. According to the membrane electrode structure, a material with relatively high mechanical strength is used as an inner-layer frame, and a material with stable chemical performance and thermal performance is arranged on the outer side for protection, so that the frame part can better support the main body membrane structure and is not influenced by chemical reactions and temperature fluctuation on two sides, and the service life is prolonged; and meanwhile, the use amount of the inner frame material with higher cost is reduced, and the material is saved.

Description

Technical field [0001] The present invention relates to a fuel cell, and more particularly relates to a membrane electrode structure, and to a fuel cell. Background technique [0002] Proton exchange membrane fuel cell having a high energy density, high energy conversion efficiency, low temperature start, low pollution outstanding advantages. The reaction typically occurs in an electrochemical membrane electrode assembly (MEA) in the catalyst layer. A membrane electrode assembly (MEA) is one of the core components of the proton exchange membrane fuel cell (PEMFC), which is a sandwich-like structure, comprising a proton exchange membrane (the PEM), electrocatalyst layer and a gas diffusion layer (GDL). MEA performance and sealing structure is a key factor of the fuel cell or fuel cell stack performance and safety impact. It is well known, the PEMFC stack is assembled using the overall configuration of the clamping force of the metal end plate metal end plate, the current collectin...
