Abstract: At least two or more energy storage units are disposed on the right and left sides, in a traveling direction, of a vehicle, and a drive unit for controlling these energy storage units is located between the two or more energy storage units. The drive unit is lower in height than the two or more energy storage units, whereby air passage are formed above the drive unit and between the two or more energy storage units.

Abstract: A discharged fuel diluter for a fuel cell includes: a dilution case which defines a dilution space; an offgas introduction pipe which penetrates the dilution case, supplying offgas discharged from the fuel cell in the case; a partitioning member having a rib provided in the dilution case; and a dilution gas pipe which penetrates the dilution case.

Abstract: A fuel cell discharge-gas processing device includes: an anode off-gas introduction path which introduces an anode off-gas discharged from an anode of a fuel cell; a dilution container which is connected to the anode off-gas introduction path, and into which the anode off-gas is introduced; and a bypass path which branches off from a cathode gas supply path for supplying a cathode gas to a cathode of the fuel cell, and is connected to the dilution container so as to bypass the fuel cell. While the fuel cell is in operation, the cathode gas supplied from the bypass path into the dilution container is discharged to an exterior of the dilution container.

Abstract: A fuel cell discharge-gas processing device that dilutes anode off-gas discharged from a fuel cell anode by mixing the anode off-gas with a diluent gas so as to produce a diluted gas and then discharges mixture of the anode off-gas and the diluent gas, includes: a dilution container; an anode off-gas introduction path; a diluent gas path through; a diluent gas emission hole; a mixed gas discharge hole; at least one partition panel; and a communication gas path, wherein the anode off-gas emission hole is provided so as to emit anode off-gas toward the partition panel.

Abstract: Hydrogen gas supplied to and then purged from a fuel cell is temporarily retained in a reservoir provided in an exhaust fuel diluter, and diluted before release into atmosphere. Cathode exhaust gas discharged from a cathode of the fuel cell is mixed to dilute the hydrogen gas, and air continues to be supplied to the cathode of the fuel cell for a specific period of time even after generation of electric power in the fuel cell is stopped, so that the hydrogen gas retained in the reservoir is continuously diluted with the cathode exhaust gas and released. Air for ventilation of the fuel cell may be used instead or in addition, to dilute and release the hydrogen gas retained in the reservoir after the generation of electric power in the fuel cell is stopped.

Abstract: An apparatus for dilution of discharged fuel of a fuel cell is provided, which has an inlet for guiding purged hydrogen gas coming from the fuel cell, a reservoir for storing the purged hydrogen gas guided through the inlet, and a cathode exhaust gas pipe penetrating the reservoir. The cathode exhaust gas pipe has a feature that it has holes inside the reservoir and is supplied with cathode exhaust gas of the fuel cell. Also the apparatus has a feature that the cathode exhaust gas pipe sucks the purged hydrogen gas stored in the reservoir through the holes and discharges the purged hydrogen gas diluted by mixing with the cathode exhaust gas.
