Abstract: Two active cell structures are prepared each comprising anode/electrolyte/cathode layers, each anode and cathode layer having embedded spaced-apart physical structures therein. Two interconnect sublayers are prepared, each comprising a layer of non-conductive material with holes formed therein and a conductor layer formed on one surface. The sublayers are placed together with the conductor layers in contact and with the holes offset to form an interconnect layer, which is then stacked between the two active cell structures. The multi-layer stack is laminated together and the anode layer of one active cell structure and the cathode layer of the other active cell structure fill the adjacent holes in the interconnect layer. The physical structures are pulled out to reveal embedded gas passages, and the multi-layer stack is sintered to form two active cells connected in series by the interconnect layer.

Abstract: A hydrogen generating device includes a first housing, a porous structure, a first flow-guiding structure and a heating unit. The first housing accommodates a solid reactant. The porous structure is disposed in the first housing. The first flow-guiding structure has first and second end portions opposite to each other. The first end portion is connected to the porous structure. The second end portion protrudes outside the first housing and is connected to the heating unit. A liquid reactant passing through the second end portion is gasified into a gaseous reactant through the heating unit. The gaseous reactant passing through the first end portion reaches to the porous structure and then is diffused from the porous structure into the first housing, so that the gaseous reactant and the solid reactant react and generate a hydrogen gas. A power generating equipment including the hydrogen generating device is also provided.

Abstract: A device and a method for controlling a cold start of a fuel cell system are provided and are capable of increasing a fuel cell load to reduce a cold start time using a kinetic energy storage method for a rotor of a motor for driving a fuel cell system. The method improves cold start performance by performing self-heating of a fuel cell stack based on an increase in an output current amount of a fuel cell and by restricting a motor torque simultaneously with generating the motor torque while applying a current to a motor when a vehicle stops to consume an output current of the fuel cell.
