Abstract: The present invention relates to a device configured for treating an exhaust gas from a fuel cell, the device including: a tube member discharging an exhaust gas from a fuel cell stack; a gas guide portion provided in a tube member and configured to guide a target gas contained in the exhaust gas to the outside of the tube member; and a guide tube spaced from the gas guide portion and provided to cover the gas guide portion such that it is possible to obtain an advantageous effect of effectively reducing a concentration of the target gas in the exhaust gas discharged from the fuel cell.

Abstract: A method for filling a tank with pressurized gaseous hydrogen from at least one source storage containing pressurized gaseous hydrogen at a first defined temperature and at a defined pressure higher than the pressure in the tank to be filled, in which hydrogen is transferred from the source storage to the tank by pressure balancing via a filling circuit having an upstream end linked to the source storage and a downstream end linked to the tank, and in which the at least one source storage exchanges heat with a member for heating the gas stored in the source storage, during at least a part of the transfer of hydrogen from the source storage to the tank, the gas contained in the source storage being heated to a second defined temperature that is higher than the first temperature.

Abstract: A boil-off gas processing system for reliably burning a boil-off gas. The system processes a boil-off gas produced from a liquid hydrogen tank which is built in a hydrogen fueled vehicle. The system includes a mixing device for introducing air into a discharge passage through which the boil-off gas from the liquid hydrogen tank passes and for mixing the air and the boil-off gas and outputting a mixed gas; a catalytic combustor for burning the mixed gas which was mixed by the mixing device, the catalytic combustor having an inlet through which the mixed gas is introduced and an outlet for discharging combustion gas; an electric heater provided at the inlet side of the catalytic combustor; and a control section for controlling energizing of the electric heater.
