ELECTRONIC CURRENT GENERATION SYSTEM COMPRISING A FUEL CELL AND A ROTARY PRESSURE SWING ADSORPTION UNIT

摘要

An electrical generating system consists of a fuel cell, and an oxygen gas delivery. The fuel cell includes an anode channel having an anode gas inlet for receiving a supply of hydrogen gas, a cathode channel having a cathode gas inlet and a cathode gas outlet, and an electolyte in communication with the anode and cathode channel for facilitating ion exchange between the anode and cathode channel. The oxygen gas delivery system is coupled to the cathode gas inlet and delivers oxygen gas to the cathode channel. The electrical current generating system also includes gas recirculation means coupled to the cathode gas outlet for recirculating a portion of cathode exhaust gas exhausted from the cathode gas outlet to the cathode gas inlet.
