Abstract

The invention discloses an air permeability testing device for a membrane electrode assembly of a new energy proton exchange membrane fuel cell. The testing device comprises a lower sealing support mechanism, an upper sealing support mechanism is arranged above the lower sealing support mechanism, and the lower sealing support mechanism and the upper sealing support mechanism are communicated withan air permeability testing mechanism, the upper end of the upper sealing supporting mechanism is connected with a clamping fixing mechanism, and the lower sealing supporting mechanism is connected with the upper sealing supporting mechanism. The upper testing plate of the upper sealing supporting mechanism is moved up and down through the clamping fixing mechanism, so that a convex sealing ringand a concave sealing ring of a supporting box form sealing and fixing of the periphery of a membrane electrode assembly, the fixing convenience and operability are improved, and the ventilation operation of the lower testing cavity and the upper testing cavity is performed through the ventilation testing mechanism, so that the pressure values at the two sides of the membrane electrode assembly are subjected to numerical feedback through a pressure gauge, so that the air permeability of the membrane electrode assembly is conveniently recorded and judged.

Description

technical field [0001] The invention relates to the field of new energy and energy saving, in particular to a gas permeability testing device for a new energy proton exchange membrane fuel cell membrane electrode assembly. Background technique [0002] The membrane electrode assembly is the core component of fuel cell power generation. The membrane electrode and the bipolar plates on both sides constitute the basic unit of the fuel cell - a single fuel cell. The performance and life of the membrane electrode are the key factors that determine the performance and life of the fuel cell system. one. Since the fuel (usually hydrogen or reformed gas containing hydrogen) and the oxidant (usually air or oxygen) are fed to both sides of the membrane electrode assembly, the membrane electrode assembly must have good chemical stability and mechanical stability, so that it can be easily Good isolation from fuel and oxidizers. Therefore, the air permeability of the membrane electrode ...
