HYDROGEN SUPPLY APPARATUS AND FUEL GAS SUPPLY APPARATUS

摘要

Disclosed is a hydrogen supply apparatus which can mix an odora nt with hydrogen gas even at a low temperature and can detect t he leakage of the hydrogen gas. The apparatus comprises a gas s torage means for storing hydrogen gas therein, an odorant-addi tion means for adding an odorant to the hydrogen gas fed from t he gas storage means, and a temperature control means for contr olling the temperature of at least one of the hydrogen gas stor ed in the gas storage means, the hydrogen gas fed from the gas storage means and the odorant.
