Abstract

The invention provides a high-temperature fuel cell test system. The high-temperature fuel cell test system comprises a gas control device for controlling gas types and gas inlet proportions of an anode gas inlet and a cathode gas inlet of a galvanic pile. A plurality of gas cylinders used for testing the performance of the high-temperature fuel cell is set, and a gas outlet of each gas cylinder is connected with the anode gas inlet and the cathode gas inlet of the fuel cell stack. A gas control device is arranged on a connecting pipeline of a gas outlet of each gas cylinder. According to thesystem, the tests of all high-temperature fuel cells and the performance tests of fuel cells with different fuel sources are satisfied, the system has the advantages of simple structure and easy realization, and the problem of high cost caused by the pertinence of a fuel cell testing system in the prior art is solved.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a high-temperature fuel cell testing system, which can realize the testing of high-temperature fuel cells such as molten carbonate fuel cells and solid oxides, and is convenient for testing their performance. Background technique [0002] High-temperature fuel cells are mainly divided into molten carbonate fuel cells and solid oxide fuel cells. Their operating temperatures are 650°C and 750°C, respectively. The reaction mechanism is an electrochemical reaction between fuel gas (hydrogen, methane, synthesis gas, etc.) and oxygen. It has the advantages of high power generation efficiency, no pollution, no noise, etc., and is the most promising power generation technology in the future. At present, universities, research institutes, enterprises and other units have invested in the research field of high temperature fuel cells and promoted the commercial application of high temperature fuel...
