[0049] The CoP / NF catalyst is divided into n=5, L=1cm, B=0.2cm, and the five parts are marked as 1#, 2#, 3#, 4#, 5# from top to bottom. Put the CoP / NF on the electrode plate 1 where the upper edge of the catalyst is flush with the 0 scale line of the first scale line 1-5, then press the L-shaped rod 7-2 to move the connecting belt 8-7, thereby pulling The slide block 8-5 moves downwards, and then pulls the propulsion wheel 8-1 to rotate through the connecting rod 8-3, thereby pushing the T-shaped guide block 10 to move to the left, and the reciprocating column 9-6 moves to the left together, and the reciprocating column 9-6 Then push the connecting column 4-3, the pressure plate 4-1 moves to the left, separate from the CoP / NF; rotate together with the pressed L-shaped rod 7-2 and the rocker 7-6, and push the connecting plate through the connecting rod 7-7 9-1. The reciprocating column 9-6 moves upward, pushes the pressure plate 4-1 to move upward to the scale line 0.2 through ...

Abstract
The invention discloses a tester and a testing method for the hydrogen evolution performance of different parts of supported catalyst, which belong to the field of electrocatalytic hydrogen evolution.The tester comprises an electrode plate, an upper pressing plate, a lower pressing plate, a supported catalyst, a base, a fixed platform, an upper rocker mechanism, a lower rocker mechanism, an upperpushing mechanism, a lower pushing mechanism, an upper driving mechanism, a lower driving mechanism, and a T-shaped guide block. By controlling the upper rocker mechanism, the lower rocker mechanism,the upper pushing mechanism, the lower pushing mechanism, the upper driving mechanism and the lower driving mechanism, the upper pressing plate and the lower pressing plate can selectively seal the untested part of the supported catalyst, exposing the tested part of the supported catalyst, and thereby the electrocatalytic hydrogen evolution performance of different parts of the supported catalystcan be tested out. The testing method and the tester are convenient to operate, the frequency of clamping is less, test error is small, moreover, the hydrogen evolution performance of different partsof the supported catalyst can be conveniently tested out, consequently, the number of high-performance parts of the supported catalyst can be increased in the process of preparation, and the utilization rate can be increased.
Description
technical field [0001] The invention belongs to the field of electrocatalytic hydrogen evolution, and discloses a method and a device for detecting the hydrogen evolution performance of different parts of a loaded catalyst, which can test the catalytic hydrogen evolution effects of different parts of the loaded catalyst. Background technique [0002] Hydrogen energy is one of the cleanest energy sources at present, how to efficiently produce hydrogen, reduce the cost of catalyst use, and improve the utilization rate are the primary problems to be solved at present. Electrolyzed water is one of the most widely used hydrogen production methods in industrial hydrogen production. At present, precious metal catalysts are widely used in electrolyzed water. However, precious metal energy is scarce, the cost is high, and there is no detection method, and the utilization rate has not reached use for maximum performance. [0003] In view of this, we have developed a detection method ...
