Description
technical field [0001] The invention belongs to the technical field of fuel cells for new energy automobile parts, and more specifically relates to a fuel cell air supply device. Background technique [0002] A fuel cell is a device that converts chemical energy into electrical energy through an electrochemical reaction. Among many types of fuel cells, proton exchange membrane fuel cells (PEMFC) have the characteristics of low operating temperature, high specific energy, fast start-up, long life, and wide application, and are considered to be the most promising. In a proton exchange membrane fuel cell, hydrogen and oxygen react electrochemically at the anode and cathode, respectively, to generate electricity. The oxygen pressure in the fuel cell is directly related to the performance of the fuel cell system. Increasing the air supply pressure (that is, the partial pressure of oxygen) can not only increase the energy density of the fuel cell system, but also reduce the size ...
