Abstract
A proton-conducting solid oxide fuel cell system includes a proton-conducting solid oxide fuel cell including an anode through which a flow of fuel is directed, and a cathode through which a flow of air containing 9% to 100% oxygen is directed, and a water recovery portion. The water recovery portion includes an anode water recovery unit to recover anode water from anode products output from the anode, and a cathode water recovery unit to recover cathode water from cathode products output from the cathode.

A proton-conducting solid oxide fuel cell system, comprising:
- a proton-conducting solid oxide fuel cell including:
- an anode through which a flow of fuel is directed;
- and
- a cathode through which a flow of air containing 9% to 100% oxygen is directed;
- and
- a water recovery portion, including:
- an anode water recovery unit to recover anode water from anode products output from the anode;
- and
- a cathode water recovery unit to recover cathode water from cathode products output from the cathode.
A method of operating a proton-conducting solid oxide fuel cell system, comprising:
- directing a flow of fuel through an anode;
- directing a flow of air containing 9% to 100% oxygen through a cathode;
- recovering anode water from anode products output from the anode via an anode condenser and an anode water separator, the anode water separated from an output fuel flow;
- and
- recovering cathode water from cathode products output from the cathode via a cathode condenser and a cathode water separator, the cathode water separated from an output air flow.
