Description

technical field [0001] The invention relates to the field of fuel cell humidification-free, in particular to a fuel cell humidification-free system device. Background technique [0002] A fuel cell is a device that converts chemical energy directly into electrical energy through an electrochemical reaction. The stable power generation of fuel cells requires the balance of water, gas and heat inside the cells. Due to the non-humidification fuel cell system, the internal moisture will be discharged from the stack along with the hydrogen and air, which will cause the membrane electrode to lose water and the power generation of the stack will be unstable. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fuel cell humidification-free system device, which can not only realize the stable operation of the fuel cell system but also realize the rapid startup of the fuel cell system at low temperature.
