Abstract
A technique includes operating an electrochemical cell as a pump, including providing a current to the cell and providing a fuel flow to an anode chamber of the cell. The technique includes communicating an anode exhaust flow from the anode chamber to an oxidizer and controlling the current to regulate a temperature of the oxidizer.
Claims8
A system comprising:
- a power source to provide a current;
- an electrochemical cell stack comprising:
- an anode chamber to communicate a fuel flow to the anode chamber, the communication producing an anode exhaust flow;
- and
- a cathode chamber to produce a purified fuel flow in response to the communication of fuel to the anode chamber and the current;
- an oxidizer to at least partially combust the anode exhaust flow;
- and
- a control subsystem to control the current to regulate a temperature of the oxidizer.
