Abstract
Composite members, a fuel cell and manufacturing method, where the composite members are mounted on a base and comprise a first insulator and a second insulator layered on either side of an interconnector, exposed in a chamfered portion on opposite corners. Between a pair of the composite members is formed an electrolyte film. An anode is formed so as to cover the anode surface of the electrolyte film and an anode-side protrusion. The anode formed at the top of anode-side protrusion is stripped, forming a flat exposed surface on the top of the anode-side protrusion. A cathode is formed so as to cover the cathode surface of the electrolyte film and a cathode-side protrusion. The cathode formed on the top of the cathode-side protrusion is stripped using a spatula, a blade, etc., forming a flat exposed surface on the top of the cathode-side protrusion.
