摘要： PROBLEM TO BE SOLVED: To provide a cooling method of efficiently cooling a compressor built in a fuel gas feeder through a cooling fan.
SOLUTION: The inside of a case in the fuel gas feeder is partitioned into two or more sections, and the compressor 2 and the cooling fan 6 are disposed in a compression chamber 1a as one section. A plate-like diffuser 21 is fitted to a leg part 22a of a support 22 supporting the compressor 2 to surround the outer periphery of a motor part 2b of the compressor 2. The cold air from the cooling fan 6 is substantially all taken in the inside of the plate-like diffuser 21, and flows along the plate-like diffuser 21 to be streamlined. Thus, the motor part 2b of the compressor 2 can be efficiently cooled. Further, the cold air in the streamlined state is sprayed to the compression part 2a so that the compression part 2a can be also efficiently cooled.
