Abstract: A fuel cell module has a fuel cell stack, an oxidant gas supply plate, a first off-gas flow channel, a first heat-insulating material and a second heat-insulating material. The oxidant gas supply plate flows an oxidant to be supplied to the fuel cell stack. An off-gas discharged from the fuel cell stack flows through the first off-gas flow channel. The fuel cell stack, the oxidant gas supply plate, and the first off-gas flow channel are located in this order in the normal direction of a main surface of the oxidant gas supply plate. The first heat-insulating material is located adjacent to the first off-gas flow channel in the normal direction. The second heat-insulating material is located outside the first heat-insulating material in the normal direction.

Abstract: A fuel cell module has a fuel cell stack and an oxidant gas supply plate. The fuel cell stack is arranged inside a housing. The oxidant gas supply plate is arranged adjacent to the fuel cell stack within the housing. The oxidant gas supply plate has an inner space. The oxidant gas supply plate is positioned separated away from an inner wall of the housing on the first direction side so that a space on the fuel cell stack side communicates with a space on the side opposite to the fuel cell stack side. The oxidant gas supply plate has a surface facing the fuel cell stack and a surface on the opposite side of the fuel cell stack, both being connected directly or indirectly to the housing.

Abstract: In fuel injection system of an internal combustion engine of a vehicle, a fuel injection valve is activated to inject pre-start fuel in response to turn-on of a main switch by a vehicle driver. A starter motor is not activated until a predetermined delay period (T.sub.D) elapses after the turn-on of the main switch. During the delay period (T.sub.D) the injected fuel is vaporized. After the delay period (T.sub.D) the vaporized fuel is taken into engine cylinders when the engine is cranked by the starter motor so that fuel is ignited in the engine easily.

Abstract: A vehicle fuel pump control apparatus controls the operating speed of a fuel pump to adjust the quantity of fuel forced to at least one fuel injector. When the required fuel quantity of the engine which is based on its operating condition is determined to be greater than a reference level predetermined in correspondence to the operating condition, the pump operating speed is increased, whereas the pump operating speed is decreased when the required fuel quantity is determined smaller than the reference level. When an insufficient fuel supply is detected during the low speed operation, the reference level is updated or readjusted to a lower level in such a manner that the required fuel quantity is determined greater than the corrected level.

Abstract: A process for curing a resin composition for the manufacture of plastic thin films by radiation curing with radioactive rays comprising mixing a radical-polymerizable resin with a filler, characterized in that at least a part of the filler is composed of a powdery ferromagnetic substance and in that said powdery ferromagnetic substance is incorporated in an amount of 1.5 to 998 parts by weight based on 100 parts by weight of the radical-polymerizable resin.
