Novel fuel cell pressure maintaining experiment bench

Abstract

The invention discloses a novel fuel cell pressure maintaining experiment bench which comprises a support. Connecting pieces arranged at two ends of the support; a clamping groove is formed in one endof the support; limiting blocks are arranged on two sides of an inserting opening; first sliding grooves are formed in the sides, close to the limiting blocks, of the inserting opening; first slidingblocks penetrating through the first sliding grooves are arranged on the sides, close to the first sliding grooves, of the limiting blocks; blocking pieces are arranged at the ends, away from the limiting blocks, of the first sliding blocks; triangular blocks are arranged on the side, close to the inserting opening, of the blocking pieces; and first springs are arranged on the triangular blocks.According to the novel fuel cell pressure maintaining experiment bench, the connecting pieces are arranged, so that the purpose that the support is simple and convenient to mount and dismount can be achieved.

Description

Technical field [0001] The present invention relates to the field of fuel cell technology, in particular to a new fuel cell packing test bench. Background technique [0002] A fuel cell is present in the fuel and oxidant chemical energy directly into the power generation apparatus, fuel and air are fed electricity fuel cell, electricity is produced strangely, it has positive and negative in appearance electrolytes, like a battery, but in fact it can not store electricity, but a power plant; with the explosive development of fuel cells, fuel cell vehicles are widely used in the industry, increasing demand for the fuel cell, the fuel cell production airtightness in itself has a great influence on the performance of the fuel cell, the fuel cell so the production process, it is necessary for the fuel cell holding pressure testing to ensure safety of the fuel cell use, and dwell experiment usually used in a test stand for placing and receiving and holding the fuel cell pressure detect...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a novel fuel cell pressure-holding test bench for the deficiencies of the prior art, so as to solve the problem that the existing fuel cell pressure-holding test bench mentioned in the background technology usually uses bolts for installation. Fixed or directly welded to achieve a stable connection to the test bench, but this method is extremely troublesome to install and disassemble, which brings inconvenience to users
