Abstract: A device for storing and releasing hydrogen gas. The hydrogen gas can be used to drive pneumatic mechanical mechanisms. The hydrogen gas is stored in a metal hydride material. The metal hydride is in thermal contact with a thermoelectric module (10) (TEM). When acted upon by an electrical current through the TEM one volume of metal hydride (12) is heated and releases hydrogen gas while a second volume of metal hydride (28) is cooled and absorbs hydrogen gas. There is a pressure difference generated between the heated volume and the cooled volume. This difference in pressure is used to drive a pneumatic-mechanical mechanism to perform work.

Abstract: A fuel cell for generating electricity by using an ion exchange membrane as electrolyte. Such fuel cells are generally arranged as a stack. Each fuel cell has a fuel electrode to which gaseous hydrogen is fed, an oxygen electrode to which oxygen is fed, an ion exchange membrane sandwiched therebetween, a fuel distribution member for supplying fuel to the fuel electrode, and an oxygen distribution member for supplying oxygen to the oxygen electrode. These fuel cells are characterized by a liquid-permeable electricity-conductive member in the form of a layer for storage and transport of water produced in the fuel cell. The fluid-permeable member is separated from the electrodes and the fuel cell is contained between outer impermeable sheets.The fuel cell assembly is part of a system that also removes heat from the assembly during its operation.

Abstract: Discloses a hydrogen compressor having two series of chambers or hydride containers specifically located in a pair of jackets adapted to contain flowing heat exchange liquid, e.g. water. The series of chambers are connected through a check valve arrangement and flow of hot and cold water through said jackets is controlled by a timing means.
