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.

Fuel cell stack

The present discussion relates to tubing clamps and systems employing tubing clamps. In one example a tubing clamp can include generally elongate top and bottom clamp bars extending between a hinge end and a clamp end. The clamp bars can apply force to tubing extending there between while being adjusted to a parallel relationship to one another.

Adjustable clamp

A proton exchange membrane fuel cell is described and which includes a proton exchange membrane having at least one gas diffusion layer which is juxtaposed relative thereto, and which is fabricated, at least in part, of a porous, electrically conductive, inorganic material which is selected from the group comprising metal diborides, metal disilicides, metal nitrides, metal carbides, and composites, laminates and solid solutions thereof.

Proton exchange membrane fuel cell

The patent relates to fuel cell systems and controlling fuel cell systems. One fuel cell system includes at least one fuel cell stack that includes multiple different serially arranged cells. The system also includes at least one component configured to effect an operating environment of the at least one fuel cell stack. The system further includes a controller configured to operate the at least one component at a primary control point relating to one or more parameters of the operating environment. The controller is further configured to temporarily adjust the at least one component to a secondary control point relating to the one or more parameters. The controller can then re-adjust the at least one component to the primary control point. The fuel cell system can achieve greater overall performance than can be obtained without the adjusting and re-adjusting.

Fuel cell stacks

A proton exchange membrane fuel cell stack and novel proton exchange membrane fuel cell module are disclosed and wherein the proton exchange membrane fuel cell stack includes a plurality of repeating, serially electrically coupled fuel cell stack modules, and which are sealably mounted together by a compressive force of less than about 60 pounds per square inch.

Proton exchange membrane fuel cell stack and fuel cell stack module

A direct liquid fuel cell is disclosed and wherein the fuel cell includes an anode fluid diffusion layer positioned adjacent to the anode side of the membrane electrode assembly, and which consists of, at least in part, a porous electrically conductive ceramic material which is substantially devoid of predetermined fluid passageways. A source of an aqueous hydrocarbon fuel solution is coupled in direct fluid flowing relation relative to the anode fluid diffusion layer, and the anode fluid diffusion layer substantially evenly distributes the aqueous hydrocarbon fuel solution across the active area surface of the anode side of the membrane electrode assembly.
