Abstract
A testing device for tubular solid oxide fuel cells (SOFC) includes a housing within which the tubular SOFC is mounted. The housing includes suitable inlets and outlets to allow a fuel gas, such as hydrogen, and an oxidant, such as air or oxygen, to interact with the anode and cathode of the tubular SOFC. In addition, the housing is formed of suitable material for placement in a heating device, such as a tubular furnace or a miniature tubular heater. A temperature sensor and computing device may monitor the temperature of the tubular SOFC in order to control the operation of the tubular heating device. In addition, the device provides electrical current collectors for coupling to the anode and cathode of the SOFC, which may be removable and reusable.
Claims8
A current collector for a tubular solid-oxide fuel cell (SOFC) having an outer electrode and a central cavity that is defined by a central electrode, the current collector comprising:
- an electrically conductive member;
- and
- a plurality of electrically conductive and flexible ribs electrically coupled to, and extending from, said member, said ribs configured to be in electrical contact with said central electrode when said member is at least partially inserted into said central cavity,
- wherein each of said ribs comprise:
- a first leg that extends from said member, wherein said first leg extends from said member at an oblique angle;
- and
- a second leg that extends from said first leg at an angle, such that said second leg is substantially parallel to a longitudinal axis of the central cavity.
