Description

technical field [0001] The invention relates to a reforming chamber for a fuel cell system and a fuel cell system, in particular to a reforming chamber for a fuel cell system and a fuel cell system for producing hydrogen by reforming methanol water. Background technique [0002] The fuel cell water-hydrogen generator uses methanol water as fuel, converts methanol water into hydrogen, passes it into the fuel cell for electrochemical reaction, and directly converts chemical energy into electrical energy, with higher energy conversion efficiency, and only emits water and a small amount of carbon dioxide, PM2 .5 emission is 0, realizing real environmental protection. It effectively solves the problem of "difficult storage and transportation and high cost" of hydrogen energy. Compared with traditional gasoline / diesel generators, it has the advantages of high-efficiency, stable and continuous power generation; no pollution, green environmental protection; low decibels, zero noise...
