Abstract:
1. In a gas supply apparatus for a polymer electrolyte fuel cell system comprising an inlet pipe through which reactant gases are supplied from a reactant gas reservoir, a reactant gas flux regulator for adjusting a flow rate of supplied reactant gases, a reactant gas supply pipe for supplying humidified reactant gases to a fuel cell, a pressure regulator for adjusting pressure of reactant gases inside the fuel cell, a coolant regulator for cooling the fuel cell, a fuel cell temperature regulator for adjusting temperature of the fuel cell, and a humidifier for humidifying the reactant gases for a polymer electrolyte fuel cell system, said humidifier comprising: a humidification vessel to which are connected a reactant gas inlet pipe for supplying reactant gas thereto, a water inlet pipe for supplying water thereto, and a reactant gas supply pipe for supplying the humidified reactant gases to the fuel cell; and a sprayer, within the humidification vessel, for spraying the reactant gases and water supplied to the humidification vessel within the vessel.
