Abstract: Disclosed herein is a fuel cell having a catalyst coated membrane (CCM) including a membrane sandwiched between an anode layer and a cathode layer; two gas diffusion layers located against respective anode and cathode layers; and two separator plates located against the respective gas diffusion layers. The fuel cell has at least one hydrogen passageway for hydrogen fuel, which extends through the CCM and disposed orthogonal relative to the plane of the layers. The hydrogen fuel is blocked from contacting the cathode layer so that the hydrogen fuel is provided to one side of the anode layer. At least one air/oxygen passageway for air/oxygen fuel extends through the CCM and disposed orthogonal relative to the plane of the layers. The air/oxygen fuel is blocked from contacting the anode layer so that the air/oxygen fuel is provided to one side of the cathode layer. A coolant pathway is in fluid communication with the layers and located to remove heat away from the layers during operation of the fuel cell.

Abstract: The dominant fuel cell design is based on using separator plates with flow fields to distribute the reaction gases parallel to the membrane. In our invention the solid electrolyte membrane fuel cell has a multitude of conduits that penetrate the catalyst coated membranes and the porous gas diffusion layers in a perpendicular direction, each conduit separated by an active area. The conduits are distributed in a repeatable parallelogram unit to create a two dimensional pattern. The conduits have appropriately positioned integrated gaskets to provide reactant gases to the anode (fuel) or cathode (oxidant) and to ensure that the anode fuel is prevented from entering the cathode side of the membrane and vice-versa. A separate conduit (in/out) for the water cooling can be added or the water cooling can be integrated to the air exhaust or the hydrogen exhaust to extract the heat from the electrochemical reaction and the reaction water.

Abstract: This device is an add-on component to an existing keyless entry system that will play a pre-recorded sound from a speaker/amplifier system mounted underneath the hood of a motor vehicle. Installable interchangeable sound cards are provided to give the device the ability to play different sounds. A digital sound amplifier is activated by the radio frequency of the automobiles factory installed keyless entry system. This is a novelty item and does not interfere with the cars existing systems.

Abstract: A fuel cell stand-by energy supply system is provided for supplying electrical power to a device operated by power from an electrical utility in the event of a power failure. The system is comprised of a microcontroller which is connected to a detector capable of detecting power failure. The microcontroller monitors this detector and one or more conditions of the device to which electrical power is fed. The microcontroller operates a fuel cell switch to connect the fuel cell d.c. supply directly to the d.c. device or to a voltage conditioning circuit to produce an operative a.c. supply which is connected to the device to continue operation thereof during the power failure. The microcontroller monitors and manages the load in relation to the fuel cell power. The microcontroller also performs an autodiagnostic of the fuel cell.
