In order to solve the problems of energy shortage and environmental pollution, it is very urgent to develop clean and efficient new energy and renewable energy sources.Hydrogen energy has become the research object of many researchers because of its high combustion calorific value, small pollution and abundant resources, among which hydrogen fuel cell vehicles are a means of effective utilization of hydrogen energy. At present, the main hydrogen supply way of gas reforming, methanol cracking, propane dehydrogenation, coke oven gas hydrogen, coal, hydrogen produced to a certain extent contain trace harmful gas
