Method for refilling and replacing catalyst in reforming chamber of reforming hydrogen-producing fuel cell

Abstract

A method for filling and replacing a catalyst in a reforming hydrogen-producing fuel cell reforming chamber, relates to the technical field of reforming hydrogen-producing fuel cells, and solves the technical problem that an existing reforming hydrogen-producing fuel cell reforming chamber needs to break the original sealed working environment for replacing a catalyst. The method for filling and replacing a catalyst in a reforming hydrogen-producing fuel cell reforming chamber includes controlling a solenoid valve of a valve port switch, an anti-suction device and a suction device. When the catalyst particles are removed, the suction device is capable of sucking the catalyst particles out of the reforming chamber; During introduction of the catalyst particle, the suction device is capableof sucking the catalyst particle into the reforming chamber, at which time the anti-suction device function to prevent the catalyst particles entering the reforming chamber from being sucked out. Thepresent invention is used to replace catalyst particles of a small fuel cell in a sealed environment.

Description

technical field [0001] The invention relates to the technical field of reforming hydrogen-producing fuel cells, in particular to a method for filling and replacing catalysts in reforming chambers of reforming hydrogen-producing fuel cells. Background technique [0002] The principle of hydrogen reforming fuel cell is an electrochemical device, and its composition is similar to that of general batteries. Its single cell consists of bipolar plate, gas diffusion layer, catalytic layer, membrane electrode and other components. The difference is that the active material of the general battery is stored inside the battery, thus limiting the battery capacity. The bipolar plate of the fuel cell is used as a channel for electron circulation. The membrane electrode protons pass through, but the electrons cannot pass through. The electrons provide an external circuit through the membrane electrode and return to the system through the plate to generate electricity. The catalytic layer...
