SOLID HIGH POLYMER TYPE WATER ELECTROLYSIS HYDROGEN PRODUCTION DEVICE

摘要

PPROBLEM TO BE SOLVED: To exceedingly improve the purity of produced gaseous hydrogen. PSOLUTION: In the solid high polymer type water electrolysis where, using a solid high polymer membrane, oxygen is generated at an anode, and hydrogen is generated at a cathode, a hydrogen line 6 for discharging produced hydrogen is provided with a catalyst-packed column 15 packed with a hydrogen oxidizing catalyst. Thus, a trace amount of gaseous oxygen intruded into gaseous hydrogen is spent on the oxidation of hydrogen, and oxygen is easy to be removed. As a result, the impurity of hydrogen is increased.
