Patent ID: 8865365

Claim:
A connector that is connected with a connector joint structure formed in separators in a fuel cell stack, the connector comprising: a connector casing; a terminal element that is provided in the connector casing and is configured to be in contact with an edge side of the separator and to be elastically deformed in an insertion direction of the connector that is orthogonal to a stacking direction of the separators, when the connector is connected with the connector joint structure; an engagement element that is formed in the connector casing and is configured to engage with the connector joint structure and restrict motion of the connector in the insertion direction when the connector is connected with the connector joint structure; and guide members that are formed in the connector casing to be extended from both sides of the terminal element in the insertion direction and respectively have opposing surfaces that are provided ahead of the terminal element in the insertion direction to face each other in a direction orthogonal to the insertion direction, wherein when the connector is connected with the connector joint structure, the guide members clamp the separator by their opposing surfaces that face each other.
