Hydrogen fuel cell stack test board and using method thereof

Abstract

The invention discloses a hydrogen fuel cell stack test board and a using method thereof, and relates to the technical field of fuel cells. The hydrogen fuel cell stack test board comprises a workingbox, wherein a rotating motor box is fixedly connected to one side of the inner wall of the working box, and a rotating motor is fixedly connected to one side of the inner wall of the rotating motor box through a motor base; and one end of an output shaft of the rotating motor is fixedly connected with a driving shaft through a coupler, and one end of the driving shaft penetrates through the rotating motor box and extends out of the rotating motor box. According to the hydrogen fuel cell stack test board and the using method thereof, when the device is used for testing a cell stack, only threaded pipes and detection pipes need to rotationally communicate with each other, and the sealing performance of threaded connection is high; and in addition, after connecting pipes communicate with thethreaded pipes, one sides of the connecting pipes can still rotate so that a worker can conveniently operate manually at any time; and the sealing performance inside and outside a pipeline is improved through sealing gaskets, so that the stability of the device during operation is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a hydrogen fuel cell stack test bench and a method for using the same. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load. Fuel cells are environmentally friendly. It uses electrochemical reaction instead of combustion (gasoline, diesel) or energy storage (battery) - the most typical traditional backup power solution. Combustion releases pollutants like COx, NOx, SOx gas and dust. As mentioned above, fuel cells only produce water and heat. If the hydrogen is produced...
