METHOD AND DEVICE FOR SUPPLYING FUEL GAS TO VEHICULAR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a method for supplying a fuel gas to a vehicular fuel cell, whereby energy is efficiently collected by using a pressure difference when decompressing the highly pressurized fuel gas.

SOLUTION: A plurality of gas turbines 25-31 are disposed in a fuel gas supply passage between a high pressure gas storage tank and a fuel cell. The highly pressurized fuel gas output from the high pressure gas storage tank is decompressed by passing it through a plurality of the gas turbines 25-31. The fuel gas output from a plurality of the gas turbines is heated by a heat exchange type heating arrangement 61. A generator 21 is driven by turning force of a plurality of the gas turbines. The output of the generator 21 is used as driving power for an electric apparatus carried on a vehicle. Required heat removal is carried out by an air conditioner carried on the vehicle by using heat exchange by the heating arrangement 61.
