Abstract: 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.

Abstract: 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.

Abstract: A housing for enclosing a fuel cell is shown and which is mounted on an adjacent enclosure having at least one substantially vertically disposed surface, and wherein the housing positions the fuel cell in spaced relation relative to an underlying supporting surface.

Abstract: A method of testing a fuel cell for gas leaks comprises providing a gas sensor in gas sensing relation to the fuel cell system, and initiating a pressure test of the fuel cell in response to the gas sensor sensing more than a predetermined amount of a target gas. A fuel cell power system comprises a fuel cell defining a fluid vessel having a fuel inlet and bleed outlet; a fuel valve upstream of the fuel inlet; a bleed valve downstream of the fuel outlet; and a pressure transducer in fluid communication with the fluid vessel, wherein a pressure test of the fluid vessel can be performed in-situ.
