PURPOSE:To operate a fuel cell to yield high outputs by utilizing regenerative braking energy in compressing the reaction gas of the fuel cell, and storing the energy in gas so that it is used in operations such as separation and refinement. CONSTITUTION:When an automobile (FC-EV) carrying a hydrogen-oxygen fuel call is braked at some speed, a reaction gas compression system 01 stops the supply of power from a fuel cell 31 to a drive motor 34 and releases the clutch 35 to open a valve 17a and close a valve 17c. Then methanol gas from a reformer 15 is forcibly fed to a fuel-gas separator 12 by a force feed pump 11. The separator 12 separates H2 from CO2 and the H2 is stored in a hydrogen tank 23. Then air A is allowed to pass through a valve 27a and O2 is separated therefrom by an oxidizer-gas separator 22 and stored in an oxygen tank 23. Therefore the concentrations of H2 and O2 for supply to the fuel cell are increased, so that high-output operation is made possible. |
