HYDROGEN SUPPLY SYSTEM AND FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen supply system and a fuel cell system, equipped with the hydrogen supply system capable of safely recycling unreacted hydrogen exhausted from the fuel cell with less energy back to the fuel cell or processing and exhausting it to the outside of the system.

SOLUTION: The hydrogen supply system is such that supplies hydrogen to a fuel cell generating power by electrochemical reaction with hydrogen and oxygen. The hydrogen supply system includes a hydrogen supply flow path 22 for supplying hydrogen to an anode side of the fuel cell, and hydrogen for returning flow path 23 for returning at least a part of unreacting hydrogen which do not react at the fuel cell to the anode side of the fuel cell, the latter mounted with an electrochemical hydrogen pump 24 electrochemically transporting hydrogen. The fuel cell system is equipped with the hydrogen supply system and the fuel cell.
