Fuel cell membrane electrode bonding device and bonding method

Abstract

The invention discloses a fuel cell membrane electrode bonding device, comprising: a lower mold base for mounting a lower frame membrane; a first positioning member for positioning a mounting positionof the lower frame membrane on the lower mold base is connected to the lower mold base. A clamp for positioning the exchange film and bonding the exchange film to the lower frame film is also included, The fixture is positioned on the lower mold base through a first positioning member so that the exchange film adsorbed thereon is positioned and attached to the lower frame film, and the lower moldbase is further connected with a vacuum adsorption device for vacuum adsorption of the exchange film so as to prevent disturbance of the exchange film in the process of the fixture detaching from thelower mold base. An upper mold base for mounting an upper frame film is arranged above the lower mold base, A second positioning member for positioning the mounting position of the upper frame film on the upper mold base is connected to the upper mold base, and the second positioning member abuts against the first positioning member during mold closing of the upper mold base and the lower mold base and during adhesion of the upper frame film to the upper surface of the exchange film so that the upper frame film is positioned with respect to the exchange film.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell membrane electrode bonding device. In addition, the present invention also relates to a fuel cell membrane electrode bonding method using the above fuel cell membrane electrode bonding device to bond membrane electrodes. Background technique [0002] A hydrogen fuel cell generates electricity through the electrochemical reaction of hydrogen fuel and an oxidant, and its core component is a membrane electrode. Membrane electrode includes two layers of carbon paper, two layers of frame membrane and proton exchange membrane coated with catalyst layer. [0003] When an electrochemical reaction occurs in a fuel cell, the proton exchange membrane is a proton permeable membrane, which is insulated, through which protons are transported from the anode to the cathode, and electrons are transported from the conductive path to the cathode. Since the hydrogen and oxygen in the cathode ...
