A solid polymer water electrolysis system is a technology to make hydrogen from water by electric power. It uses solid polymer electrolyte nembrane, which has proton conductivity. This system has characteristic of low operation temperature, can make high purity hydrogen and oxygen, and needs only water and electric power. Electrolysis is electrochemical reaction with heat generation. So thermal design of large size module is very important to make high performance system, because its performance varies with temperature and it has upper limit temporature about 120℃. A solid polymer water electrolysis module is composed many stacked cells and separators. A performance simulator of solid water electrolysis module was made, considering three-dimensional distribution of tempeorature and current density. The influences of module size and operate conditions upon module performance were studied.
