Abstract: An information processing device includes an acquisition unit which acquires use history information indicating a use history of a vehicle for a plurality of items, a derivation unit which derives the output decrease amount for each of the items based on use history information and output decrease characteristic information, a factor-specific output decrease amount estimation unit which estimates the output decrease amount for each of output decrease factors based on the output decrease amount for each of the items and output decrease factor information, and a control unit which executes control to increase a flow rate of a pump when any one of output decrease amounts for each of the output decrease factors is equal to or larger than a threshold value, compared with when where all of the output decrease amounts for each of the output decrease factors are less than the threshold value.

Abstract: Provided is a fuel cell including a plurality of stacked unit cells, each including a membrane-electrode assembly and a separator stacked on the membrane-electrode assembly. The separator includes a separator plate that overlaps the membrane-electrode assembly when seen from a stacking direction, a first terminal portion configured to protrude from the separator plate toward an outer side in a plane direction, a plate covering portion configured to cover an outer peripheral edge of the separator plate, and a terminal covering portion configured to be formed integrally with the plate covering portion and covers the first terminal portion. A plurality of the first terminal portions, which are adjacent to each other in the stacking direction, include offset portions which shift from each other when seen from the stacking direction, and are covered with the terminal covering portion.

Abstract: A fuel cell system in which fuel cell flooding is eliminated by providing necessary flow speed of fuel gas within a channel while improving system efficiency of the fuel cell by re-circulating unreacted fuel gas, which has been discharged externally from a circulation channel in order to provide the flow speed within the channel. An exhaust gas storage unit which stores exhaust gas is disposed in an exhaust gas recovery channel, to store exhaust gas discharged from the anode channel of the fuel cell. Fuel consumption can be improved by re-supplying the exhaust gas to the fuel cell again. Furthermore, an exhaust storage unit is maintained at a negative pressure. This allows the flow speed of reactant gas flowing through the channel for fuel gas to be increased at the time of opening the control valve connected to the exhaust gas storage unit. Such an arrangement allows water droplets or the like remaining within the anode electrode of the fuel cell to be removed, thereby suppressing flooding.
