Fuel cell power plant pumps oxygen or air into compression housing, compressed gas flows through cell, expands, and gas under reaction pressure in cell generates mechanical energy

摘要

The engine has at least one mechanical pump with at least one variable volume chamber, an inlet and outlet control and a crank mechanism connected to a fuel cell to operate in at least two cycles. Oxygen or air is pumped into a compression housing and compressed. The compressed gas flows through the cell and expands and the gas under increased pressure produced by the chemical and exothermal reaction in the fuel cell generates mechanical energy.
