Abstract
A fuel cell system includes one or more fuel cells, one or more of the fuel cells including an electrolyte material, a first electrode and first electrical conductor on one side of the electrolyte material and a second electrode and second electrical conductor on the other side of the electrolyte material, the electrolyte material of a fuel cell defining a fuel space, the fuel space being connected to a fuel supply, within the system, the one or more fuel cells being provided within an oxidant space, the oxidant space being connected to an oxidant supply, the oxidant space and one or more fuel spaces being provided within a gas impermeable barrier, the gas impermeable barrier defining a heating space outside of the gas impermeable barrier, a source of heat being provided in the heating space.
Claims11
A fuel cell system including one or more fuel cells, the system comprising:
- one or more of the fuel cells including an electrolyte material, a first electrode and first electrical conductor on one side of the electrolyte material and a second electrode and second electrical conductor on the other side of the electrolyte material, the electrolyte material of a fuel cell defining a fuel space, the fuel space being connected to a fuel supply,
- within the system, the one or more fuel cells being provided within an oxidant space, the oxidant space being connected to an oxidant space being connected to an oxidant supply, the oxidant supply, the oxidant space and one or more fuel spaces being provided within a gas impermeable barrier, the gas impermeable barrier defining a heating space outside of the gas impermeable barrier, a source of heat being provided in the heating space.
A method of producing a fuel cell system, the method comprising:
- producing one or more fuel cells, one or more of the fuel cells comprising an electrolyte material, a first electrode and first electrical conductor to one side of the electrolyte material and a second electrode and second electrical conductor to the other side of the electrolyte material, the electrolyte material defining a fuel space;
- connecting the fuel space of the one or more fuel cells to a fuel supply;
- providing a gas impermeable barrier around the fuel cells, the barrier defining within it an oxidant space and outside it a heating space;
- and
- connecting the oxidant space to an oxidant supply.
A method of producing electricity, the method comprising:
- providing a fuel cell system, the system comprising one or more fuel cells, one or more of the fuel cells including an electrolyte material, a first electrode and first electrical conductor on one side of the electrolyte material and a second electrode and second electrical conductor on the other side of the electrolyte material, the electrolyte material of a fuel cell defining a fuel space;
- within the system, the one or more fuel cells being provided within an oxidant space, the oxidant space and the one or more fuel spaces being provided within a gas impermeable barrier, the gas impermeable barrier defining a heating space outside of the gas impermeable barrier;
- supplying fuel to the fuel space, an oxidant to the oxidant space and applying heat to the heating space.
