Problems solved by technology

[0004] Part of the equipment in the air system, such as air compressors, intercoolers, etc., will also generate a lot of heat due to continuous operation. Temperature control, on the one hand, will affect the normal operation of the equipment due to the high operating temperature, on the other hand, when the gas circulates into the equipment, it will also increase the temperature of the gas, which will increase the burden of temperature control on the gas circulating in the air system

The heat exchange requirements of the air compressor and the intercooler on different time sequences are met; the ion concentration around the intercooler is reduced, and the working efficiency of the intercooler is guaranteed.

Description

technical field [0001] The present application relates to the technical field of fuel cells, in particular to a marine fuel cell cooling system and a control method thereof. Background technique [0002] At present, ship navigation mainly relies on marine diesel generators to provide power, and its power generation produces a large number of pollution sources, which exacerbates the withering of resources and the deterioration of the ecological environment. A fuel cell is a device that directly converts chemical energy in fuel into electrical energy through electrochemical reactions. Compared with traditional diesel generators, it does not have the process of fuel combustion and is not affected by the Carnot cycle. The energy conversion process does not generate Substances that pollute the atmosphere have gained more and more favor in the industry. However, the energy conversion process of the fuel cell will generate heat. Reasonable control of the temperature of the inlet a...
