Embodiment Construction

[0030] Examples, see e.g. Figure 1 to Figure 8 Shown, a kind of spraying fixture that is used for the membrane electrode of proton exchange membrane fuel cell comprises the first frame 2 and the second frame 3 that are rectangular spraying spacer frame 1 and up and down setting; Described spraying spacer frame 1 is shaped as A plurality of first spacer strips 11 linearly and uniformly distributed in the left and right directions and a plurality of second spacer strips 12 linearly and uniformly distributed in the up and down direction;

[0031] The middle part of the first frame 2 is formed with a first rectangular step through hole 21, and the middle part of the second frame 3 is formed with a second rectangular step through hole 31. The proton exchange membrane 9 is clamped in the small part of the first rectangular step through hole 21. Between the end face of the end hole and the end face of the small end hole of the second rectangular step through hole 31;

Abstract

The invention relates to the technical field of fuel cells, and discloses a spraying jig for a membrane electrode of a proton exchange membrane fuel cell, which comprises a spraying isolation frame, a first frame and a second frame, a plurality of first isolating bars and a plurality of second isolating bars which are vertically arranged are formed on the spraying isolating frame; a first rectangular step through hole is formed in the first frame, a second rectangular step through hole is formed in the second frame, and the proton exchange membrane is clamped between the end face of the first rectangular step through hole and the end face of the second rectangular step through hole; the spraying isolation frame can be inserted into the large end hole of the first rectangular step through hole or the large end hole of the second rectangular step through hole in a sleeved mode. The frame is made of aluminum alloy and can be used for a long time without bending deformation; and meanwhile, the aluminum alloy frame can be turned over after being sprayed for the first time, so that the second surface can be directly sprayed, and the spraying efficiency and the spraying quality can be effectively improved.

Description

Technical field: [0001] The invention relates to the technical field of fuel cells, in particular to a spraying tool for membrane electrodes of proton exchange membrane fuel cells. Background technique: [0002] With the current energy shortage and environmental pollution becoming more and more serious, the development of new sustainable and environmentally friendly energy conversion devices has become a current research hotspot. A fuel cell is an energy conversion device that can directly convert chemical energy into electrical energy. Since its reaction is essentially equivalent to the reverse reaction of electrolyzing water, the final product of the reaction is environmentally friendly, and the fuel source is extensive and sustainable. The energy conversion of fuel cells is not limited by the Carnot cycle. Theoretically, the energy conversion efficiency can reach 90%, and the actual use efficiency is 40%-60%, which is 2-3 times that of ordinary internal combustion engines...
