HIGH-PRESSURE HYDROGEN TANK CAPABLE OF HYDROGEN PRODUCTION AND FUEL BATTERY VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a high-pressure hydrogen tank capable of hydrogen production which produces high-pressure hydrogen within it and is easily usable by mounting in e.g. a fuel battery vehicle and a fuel battery vehicle.SOLUTION: In a high-pressure hydrogen tank, a partition member 12 partitions the inside of a tank body 11 into two divisions with a solid polymer electrolyte membrane 29. The tank body 11 has a water supply port 11a and an exhaust port 11b in one division 31 and an air outlet 11c in the other division 32. When the one division 31 becomes higher in internal pressure than the other division 32, the partition member 12 operates under the pressure difference to close the exhaust port 11b. Water supply means 13 can supply water from the water supply port 11a to the one division under at a specified pressure. Electrolysis means 14 has an anode 33 on one side and a cathode 34 on the other side of the solid polymer electrolyte membrane. Control means 15 stops electrolysis and water supply when the other division 32 reaches a set pressure.
