Fuel battery membrane electrode leak detector

Abstract

The invention comprises a machine frame, an upper detection board and a lower detection board. It features the following: the upper detection board is connected to the elastic unit through insulation material; said elastic unit is mounted on the baffle plate in the machine frame; the lower detection board whose undersurface is attached with insulation material is located on the base; there is a voltage measuring device located between the upper detection board and lower detection board.

Description

technical field [0001] The invention relates to a detection device, in particular to a leak detector for fuel cell membrane electrodes. Background technique [0002] With the increasing tension of fossil energy and the increasing importance of environmental protection, clean, efficient, hydrogen-fueled fuel cell (Fuel Cell, FC) technology has become a new energy source for sustainable development in the future, and is increasingly valued by governments around the world . [0003] The core component of the fuel cell is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode consists of a proton exchange membrane and two conductive porous diffusion materials (such as carbon paper) sandwiched on both sides of the membrane. A finely dispersed catalyst (such as metal platinum) that can initiate an electrochemical reaction is evenly distributed on the two boundary surfaces that are in contact with the conductive material. On both sides of...

Problems solved by technology

This kind of membrane electrode vacuum leak detection device has a problem that the membrane electrode is easily damaged due to excessive vacuum during detection, and a slight deviation in the matching degree of the upper and lower sealing rings will cause false detection. In order to be able to accurately dock and match the operation process is complex and cumbersome.
