Abstract

The invention discloses an air supply and water supply system for a fuel cell test board. The air supply and water supply system comprises a compressed air branch path and an oxygen source branch pathwhich are mutually connected in parallel, a reaction gas supply branch path, a nitrogen pipeline, a humidifying branch path, a galvanic pile cooling water circulating branch path, a water supplantingbranch path and an exhaust gas emission branch path. Through switching of an air source, the air supply and water supply system for the test board can be used for the testing of a hydrogen-air fuel cell stack and also can be used for the testing of a hydrogen-oxygen fuel cell stack; and the inlet temperature of cooling water at the galvanic pile of the test board can be adjusted by controlling the temperature of a pure water tank and the flow of external cooling water. The test board using the air supply and water supply system has the characteristics of operating mode diversification, high adaptability, high reliability, convenient maintenance, low operating cost and the like.

Description

technical field [0001] The invention belongs to the technical field of fuel cell testing, and relates to an air and water supply system for a fuel cell test bench. Background technique [0002] A fuel cell is an efficient and environmentally friendly power generation device that can directly convert chemical energy stored in fuel and oxidant into electrical energy. Today, when the environment and energy have attracted much attention, fuel cells have increasingly attracted the attention of governments and scientific and technical personnel in various countries. In recent years, fuel cells have gradually been widely used on the basis of breaking through a number of key technologies. Hydrogen is the best fuel for fuel cells. In the future era of hydrogen economy, fuel cells are the best energy conversion devices for converting hydrogen energy into electrical energy. [0003] When the fuel cell is working continuously, fuel and oxidant (such as hydrogen, oxygen or air) must be...
