Description
technical field [0001] The invention belongs to the technical field of new energy and relates to a hydrogen fuel cell, in particular to a test system suitable for an air-cooled hydrogen fuel cell. Background technique [0002] Hydrogen fuel cells generally use hydrogen or reformed hydrogen as fuel, and air or oxygen as oxidant to convert chemical energy into electrical energy. Hydrogen fuel cells are divided into air-cooled type and water-cooled type according to the heat dissipation method. The flow rate, temperature and humidity of hydrogen, the flow rate, temperature and humidity of air, as well as the temperature and other physical parameters of the fuel cell stack itself have an important impact on the normal operation and power generation efficiency of the fuel cell. [0003] Patent 201610152403.7 provides a test platform for testing the water-cooled fuel cell hydrogen system, which can simulate the state of the hydrogen system when the fuel cell system is running, so...
