Abstract
A rotating fuel cell has a mounting with bearing means defining a rotary axis. A shaft with a longitudinally-extending bore is supported for rotation on the bearings. At least one PEM fuel cell assembly is mounted on the shaft and insulated therefrom, and also has a gas passageway in register with a radially-extending port in the shaft. Connections are provided for admitting hydrogen gas to the hollow bore. Air (oxygen) is supplied to the exterior of the PEM fuel cell assembly. The shaft and the PEM fuel cell assembly is rotated about the axis.
