Abstract
An electric vehicle includes a battery and one or more solid oxide fuel cells. A fuel line provides fuel to the solid oxide fuel cell from a first chamber of a fuel tank. An exhaust line returns exhaust fluid from the solid oxide fuel cell to a second chamber of the fuel tank. A refrigeration system is in thermal communication with the exhaust line to remove heat from and condense the exhaust fluid before the exhaust fluid enters the fuel tank.
Claims21
A system comprising:
- a solid oxide fuel cell;
- a fuel tank, wherein said fuel tank includes at least a first chamber separate from a second chamber;
- a fuel line extending between said fuel tank and said solid oxide fuel cell, wherein said fuel line is configured to supply fuel from the first chamber of said fuel tank to said solid oxide fuel cell;
- an exhaust line extending between said fuel tank and said solid oxide fuel cell, wherein said exhaust line is configured to return exhaust fluid including CO2 from said solid oxide fuel cell to said second chamber of said fuel tank;
- a refrigeration system in thermal communication with the exhaust line, wherein said refrigeration system includes ammonia as a heat transfer fluid;
- wherein said refrigeration system is configured to condense the CO2 in the exhaust line;
- and
- wherein the condensed CO2 is stored in said second chamber of said fuel tank as a liquid.

9-20. (canceled)
A system comprising:
- a solid oxide fuel cell;
- a fuel tank, wherein said fuel tank includes two separate chambers and a movable separator between said two separate chambers;
- a fuel line extending between said fuel tank and said solid oxide fuel cell, wherein said fuel line is configured to supply fuel from said fuel tank to said solid oxide fuel cell;
- an exhaust line extending between said fuel tank and said solid oxide fuel cell, wherein said exhaust line is configured to return exhaust fluid including CO2 from said solid oxide fuel cell to said fuel tank;
- and
- a refrigeration system in thermal communication with the exhaust line, wherein said refrigeration system is configured to condense the CO2 in the exhaust line.
3 more elements
A method of operating an electric vehicle, comprising
- providing power to drive the electric vehicle, wherein the power is provided by a battery having a battery capacity;
- activating one or more of a plurality of solid oxide fuel cells to recharge the battery, wherein said plurality of solid oxide fuel cells are electrically connected to said battery;
- wherein the one or more of said plurality of solid oxide fuel cells are activated when the battery capacity is below a threshold value and the electric vehicle has maintained a minimum average speed for a predetermined amount of time.
