Abstract: An example fuel cell cabinet, comprises: a fuel cell case provided with an opening and accommodating a fuel cell; a lid part covering the opening; a first fixing part fixing a first end of the lid part to the fuel cell case by a predetermined force; and a second fixing part fixing a second end different from the first end of the lid part to the fuel cell case by a force weaker than the predetermined force.

Abstract: A gas-liquid separator capable of decreasing the height dimension thereof and a fuel cell system suitable for the gas-liquid separator are provided. In a gas-liquid separator, an introduction pipe connected to a main pipe includes an enlarged portion. A passage cross-sectional area of the enlarged portion is larger than that of an inlet pipe. An exhaust gas of hydrogen including impurities such as water discharged from a fuel cell stack flows from the inlet pipe and the speed of the exhaust gas in the enlarged portion decreases. As the speed at which the exhaust gas flows into the main pipe decreases, a ratio in which water falls downward increases. For this reason, even when the dimension of the gas-liquid separator in the height direction is shortened, a water separating rate can be maintained. The exhaust gas of hydrogen from which water is separated is reused in the fuel cell stack.

Abstract: A sheet-discharge device, including: a sheet-discharge mechanism having a discharge opening from which a sheet is discharged in a discharge direction; a stopper having a hitting portion against which a leading edge, in the discharge direction, of the discharged sheet hits, so that the sheet is bounced back; a discharge tray having a support surface on which the sheet bounced back by the stopper is supported; and a sheet-discharge controller configured to control the sheet-discharge mechanism such that the discharged sheet flies above the support surface, wherein the hitting portion is provided at a position where a one-side portion of the leading edge first hits the hitting portion, the one-side portion of the leading edge being nearer to a one-side end of the sheet than a center of the leading edge in an orthogonal direction parallel to a horizontal plane and orthogonal to the discharge direction.
