[0027] Examples of fuel cell systems
[0028] This embodiment provides a fuel cell system, and the point of the invention lies in the replacement method of the air filter.
[0029] Such as image 3 As shown, the fuel cell system includes an air filter 2, an air compressor 4 and an air intercooler 6, the gas output end of the air filter 2 is connected to the gas input end of the air compressor 4 through a pipeline, and the gas of the air compressor 4 The output end is connected to the gas input end of the air intercooler 6 through a pipeline. The gas input end of the air filter 2, that is, the air inlet is connected to the outside atmosphere, and an air flow meter is usually built in the pipeline between the gas output end of the air filter 2 and the gas input end of the air compressor 4 (in the figure for illustration). In order to detect the replacement time of the air filter 2 to replace it, a pressure sensor 1 is installed at the gas input end of the air filter 2, that i...
