Abstract: Disclosed herein is a method for producing fluid flow field plates with complex flow field geometries. The method includes locating an electrically conductive sheet on top of another electrically conductive sheet so that they are in intimate contact with each other. The sheets are sealed together, with a manifold opening cut through the sheets. A channel for a fluid is created by kiss cutting through the first sheet so that the channel is in fluid communication with the manifold opening.

Abstract: A positioning device for a picture stabilizer for the controlled movement of a carrier with respect to a base includes a first coupling element, a second coupling element, a first transmission unit, and a second transmission unit. The first coupling element, by way of a first suspension, is assembled in a movable manner with respect to the base and is movable by a first linear drive. The second coupling element, by way of a second suspension, is assembled in a movable manner with respect to the base and is movable by a second linear drive. The first transmission unit transmits movement of the first coupling element onto the carrier and the second transmission unit transmits movement of the second coupling element onto the carrier. The first coupling element and the second coupling element in each case have a movability with essentially exactly one translatory degree of freedom.

Abstract: Disclosed herein is a combined fuel cell and heat exchanger stack assembly. The assembly includes two electrically conductive plates, each plate having two sets of spaced apart fluid openings. The two sets of openings are spaced apart from each other. One or more fluid channels fluidly connect one fluid opening in one set with one fluid opening in the other set. A heat exchanger plate has two sets of spaced apart heat exchanger fluid openings. The two sets of heat exchanger openings are spaced apart from each other. One or more fluid channels fluidly connect one heat exchanger fluid opening in one set with one heat exchanger fluid opening in the second set. The heat exchanger plate is sandwiched between the electrically conductive plates so that the spaced apart fluid openings in the plates and the fluid channels are in fluid communication with each other.

Abstract: A dispensing apparatus for a cryogenic fuel includes a cryogenic compression tank with an amount of liquid hydrogen in it. The liquid hydrogen is held at a first temperature and first pressure. The compression tank has a liquid hydrogen inlet and a gaseous hydrogen outlet. A heater is mounted in the compression tank for heating the liquid hydrogen therein to a second temperature and a second pressure. The second temperature and pressure are higher than the first temperature and pressure so that the liquid hydrogen is converted to gaseous hydrogen. A closable line is connected to the gaseous hydrogen outlet and extends from it. The closable line is in fluid communication with a receiving tank when the line is opened so that the gaseous hydrogen flows from the compression tank to the receiving tank.
