Sensor attachment apparatus

Abstract

A sensor attachment apparatus including a flow path forming member made of an insulating material and forming a gas flow path through which a reaction gas for a fuel cell flows, a spacer member made of a conductive material and mounted in a connection hole portion provided in the flow path forming member, a sensor attached to the spacer member, and a ground wire attached to the spacer member. The spacer member has a first end portion with a communication port facing an opening of the connection hole portion and a second end portion with a sensor attachment portion where the sensor is attached, extends in a predetermined direction intersecting a flow direction of the reaction gas from the first end portion to the second end portion, and is configured to form a closed space communicating with the gas flow path through the communication port.
