US Patent 10957929 Fuel cell stack

A fuel cell system includes a first plurality of fuel cells having a cathode and an anode. The plurality of fuel cells is configured to produce electrical power having a current and a voltage output. The plurality of fuel cells includes a first conductive plate and a second conductive plate. A shunt is electrically connected to the first conductive plate and the second conductive plate for shunting voltage output between the cathode and the anode. The shunt is mounted to, and supported by, the plurality of fuel cells. The shunt is connected to a control mechanism to control a shorting of one or more fuel cells of the plurality of fuel cells. The control mechanism is mounted to, and supported by, the plurality of fuel cells.
