Abstract
An electrochemical cell apparatus that can operate as either a fuel cell or a battery includes a cathode compartment, an anode compartment operatively connected to the cathode compartment, and a carbon fuel cell section connected to the anode compartment and the cathode compartment. An effusion plate is operatively positioned adjacent the anode compartment or the cathode compartment. The effusion plate allows passage of carbon dioxide. Carbon dioxide exhaust channels are operatively positioned in the electrochemical cell to direct the carbon dioxide from the electrochemical cell.

An electrochemical cell apparatus that can operate as either a fuel cell or a battery, the electrochemical cell producing carbon dioxide;
- comprising:
- a cathode unit;
- an anode unit operatively connected to said cathode unit;
- a carbon fuel cell section connected to said anode unit and said cathode unit;
- an effusion plate positioned in operative position with said anode unit or said cathode unit, said effusion plate allowing the passage of carbon dioxide;
- and
- carbon dioxide exhaust channels in the electrochemical cell in operative position with said effusion plate to direct the carbon dioxide from the electrochemical cell.
An electrochemical cell apparatus that can operate as either a fuel cell or a battery, the electrochemical cell producing carbon dioxide;
- comprising:
- a bipolar plate;
- a cathode current collector;
- an anode current collector operatively connected to said cathode current collector and said bipolar plate;
- a carbon fuel cell unit operatively connected to said anode current collector and said bipolar plate;
- an effusion plate positioned adjacent said anode current collector, said effusion plate allowing the passage of the carbon dioxide;
- and
- carbon dioxide exhaust channels in the electrochemical cell positioned adjacent said anode current collector, said carbon dioxide exhaust channels operatively connected to said effusion plate to direct the carbon dioxide from the electrochemical cell.
