Description
technical field [0001] The embodiments of the present application relate to the technical field of fuel cells, and in particular to a thermal management system and control method of a fuel cell. Background technique [0002] Fuel cells generate electricity by reacting hydrogen gas with oxygen in the air. The product of the reaction is water. Not limited by the Carnot cycle, the efficiency can reach more than 50%. Therefore, it is not only environmentally friendly but also energy-saving, and is suitable for fuel cell powered vehicles. [0003] In applications such as fuel cell powered vehicles, desired power is generated by stacking a plurality of fuel cells in a fuel cell stack. Generally, in a fuel cell, hydrogen gas supplied to the anode side reacts with oxygen (eg, air) on the cathode side to generate electricity. This electrochemical reaction also results in heat generation in the fuel cell stack. Therefore, it is important to maintain the temperature of the fuel cel...
