Abstract
A fuel cell includes sensors. Each sensor includes: a sensor portion provided on at least one of separators, a frame member, and an electrolyte membrane; and a wiring portion connected to the sensor portion and extending to an outer peripheral portion of one of the separators or an outer peripheral portion of a membrane electrode assembly. The sensor further includes a base insulating film covering a sensor arrangement region; wiring patterns laminated on the base insulating film; and a covering insulating film covering the wiring patterns and portions of the base insulating film not covered with the wiring patterns.
Claims1
A fuel cell comprising:
- a membrane electrode assembly including an electrolyte membrane, an anode provided on one surface of the electrolyte membrane, and a cathode provided on another surface of the electrolyte membrane;
- a frame member surrounding an outer peripheral portion of the membrane electrode assembly;
- a pair of separators sandwiching the membrane electrode assembly;
- and
- a sensor including:
- a sensor portion provided on at least one of the separators, the frame member, or the electrolyte membrane;
- and a wiring portion connected to the sensor portion and extending to an outer peripheral portion of one of the separators or the outer peripheral portion of the membrane electrode assembly,
- wherein the sensor further includes:
- a base insulating film that covers a surface of a sensor arrangement region in which the sensor is arranged;
- a wiring pattern laminated on the base insulating film;
- and
- a covering insulating film that covers the wiring pattern and a portion of the base insulating film that is not covered with the wiring pattern,
- wherein the sensor portion is provided on a surface of the electrolyte membrane,
- wherein the wiring portion includes:
- a first wiring portion extending along a surface of the electrolyte membrane and connected to the sensor portion;
- and
- a second wiring portion extending along a surface of the separator, and
- wherein the first wiring portion and the second wiring portion are electrically connected to each other by bringing a first terminal portion where the wiring pattern of the first wiring portion is exposed from the covering insulating film and a second terminal portion where the wiring pattern of the second wiring portion is exposed from the covering insulating film into face-to-face contact with each other.
