Fuel cell array and fuel cell inspection method

A method of inspecting a fuel cell array including a plurality of fuel cells,

• the fuel cell including
• a first electrode layer,
• a solid electrolyte layer,
• a second electrode layer, and
• a connection element having one end connected to the first electrode layer,
• the fuel cell array further including a first wiring and a second wiring,
• the first wiring being connected to the second electrode layer of each of the fuel cells,
• the second wiring being connected to the other end of the connection element of each of the fuel cells, and
• the connection element having a structure in which a conductive layer is sandwiched between two electrodes,
• the method comprising
• a step of applying a voltage between the first electrode layer and the second electrode layer to the fuel cell in which the connection element is turned off to monitor an output current, thereby determining whether the fuel cell applied with the voltage is in short-circuit failure, or
• a step of generating electricity from the fuel cell with the connection element turned off to monitor an output voltage, thereby determining whether the electricity-generated fuel cell is a defective product or not.
