Compressor-regenerator combination for fuel cell has displacement compression and regenerative mechanism parts connected to fuel cell delivery and gas output sides respectively

摘要

The compressor-regenerator combination has a displacement type compression mechanism part (C) connected to a delivery side for fuel cell (F) gas containing. oxygen and a displacement type regenerative mechanism part (E) connected to the gas output side of the fuel cell. A closed compression chamber (14) and a closed regenerative chamber (24) have a vol. ratio of 1.25 to 3.
