A fuel cell includes a membrane electrode assembly, a first plate separator and a second plate separator on opposite sides of the membrane electrode assembly and a voltage sensor for detecting a cell voltage relative to opposite sides of the membrane electrode assembly. A transmitter is coupled to the sensor and configured to wirelessly transmit an indication of the cell voltage.

Fuel cell information monitor and data transfer

A fuel cell system includes a membrane electrode assembly, a first plate separator and a second plate separator on opposite sides of the membrane electrode assembly. The first plate separator and the second plate separator have exterior ends laterally spaced from the membrane electrode assembly. A first gas diffusion layer is located between the first plate separator and the membrane electrode assembly. A second gas diffusion layer is located between the second plate separator and the membrane electrode assembly. The sub-gasket extends laterally from the membrane electrode assembly. A first seal is located between the first plate separator and the sub-gasket. A conductive trace is attached to the sub-gasket and extends laterally on the sub-gasket away from the first seal and upwardly away from the subgasket to contact the first plate separator.

Integrated circuit for diagnostics

A fuel cell system includes a membrane electrode assembly, a first plate separator and a second plate separator on opposite sides of the membrane electrode assembly. The first plate separator and the second plate separator have exterior ends away from the membrane electrode assembly. A first gas diffusion layer is located between the first plate separator and the membrane electrode assembly. A second gas diffusion layer is located between the second plate separator and the membrane electrode assembly. The sub-gasket extends from the membrane electrode assembly laterally toward at least one of the exterior ends. A first seal is located between the first plate separator and the sub-gasket. A conductive trace is attached to the sub-gasket and extends on the sub-gasket from an exterior side of the first seal to a location on an interior side of the first seal.
