Fuel cell membrane electrode production device

Abstract

The invention discloses a fuel cell membrane electrode production device, which comprises an annular base, an end face gear rotationally connected to the upper end of the annular base, an annular gear fixedly connected to the inner side of the end face gear, a cross-shaped sliding seat fixedly connected to the inner side of the annular base and a spraying device arranged over the cross-shaped sliding seat. When a first stepping motor works, a motor shaft on the first stepping motor drives a first gear to rotate, when the first gear rotates, an end face gear at the upper end of an annular base can be driven to rotate through an annular gear, and when the end face gear rotates, a second gear and threaded rods can be driven to rotate. Thread directions of the four threaded rods are set, one group of opposite transmission plates can simultaneously move towards the inner side, and the other group of opposite transmission plates can simultaneously move towards the outer side, so that the positions of the proton exchange membranes above the transmission plates can be changed, four proton exchange membranes can be sprayed at one time, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the related technical field of fuel cell membrane electrode production, and in particular relates to a fuel cell membrane electrode production device. Background technique [0002] Membrane electrodes are generally a combination of proton exchange membranes, catalysts and carbon paper. The proton exchange membrane is usually sandwiched between two carbon papers, and the catalyst can be coated on the outside of the proton exchange membrane or embedded between the carbon paper and the proton exchange membrane. In the prior art, the patent document with the application number 201910054129.3 and the name of a catalyst spraying equipment for fuel cell membrane electrode production is disclosed. The push rod drives the electric nozzle on the fixed plate to move outward and inward, and the cylinder drives the slider to slide, and then drives the electric nozzle on the fixed plate to move left and right, so that the electric nozzle mo...

In the prior art, the patent document with the application number 201910054129.3 and the name of a catalyst spraying equipment for fuel cell membrane electrode production is disclosed. The push rod drives the electric nozzle on the fixed plate to move outward and inward, and the cylinder drives the slider to slide, and then drives the electric nozzle on the fixed plate to move left and right, so that the electric nozzle moves along the hydrogen surface of the proton exchange membrane. Any corner, and spray inward along its outer edge to the center point, to spray the surface of the proton exchange membrane, but in the prior art, the electric nozzle can only spray a single proton exchange membrane at a time, and the working Low efficiency, in view of this, the present invention proposes a fuel cell membrane electrode production device
