There is provided a hydrogen consumption quantity measurement system that, even in a case in which there is a possibility that leakage hydrogen is contained in exhaust gas from a fuel cell or a hydrogen engine, makes it possible to accurately determine a total quantity of hydrogen consumption of the fuel cell without having to modify a vehicle or the like. This hydrogen consumption quantity measurement system measures a hydrogen consumption quantity in a test body, which is formed by a moving body or portion thereof that includes a hydrogen reactor that causes hydrogen to undergo a chemical reaction, and that utilizes energy obtained from this chemical reaction, and includes an oxygen concentration sensor that measures a concentration of oxygen contained in exhaust gas from the test body.

A method for treating hydrogen-containing and oxygen-containing residual gases of fuel cells, wherein the residual gases are fed to a gas circuit, and a residual gas mixture resulting therefrom is circulated in the gas circuit by a device for converting hydrogen and oxygen to water. In order to reduce the amount of hydrogen and oxygen in the residual gas mixture, at least part of the residual gas mixture is discharged from the gas circuit.

The invention provides a hydrogen sensing device capable of preventing sensor sensitivity decreases.A hydrogen sensor 150 detects the hydrogen in an exhaust pipe and is installed in a divergent pipe DP. Flowing through the exhaust pipe is off-gas discharged from the fuel cell of a fuel cell vehicle. In order to decompose the siloxanes contained in the gas, a siloxane decomposing material 130 is placed upstream of the hydrogen sensor 150 inside the divergent pipe DP. Also, an SiO2 capturing material 140 is placed between the siloxane decomposing material 130 and the hydrogen sensor 150, so that the SiO2 capturing material can capture the SiO2 resulting from the decomposition of siloxanes by the siloxane decomposing material 130.

摘要:
An apparatus for recirculation of a cathode gas in a fuel cell arrangement having a cathode gas supply for supplying the cathode gas to a cathode area, and a cathode gas outlet for carrying the partially consumed cathode gas out of the cathode area, includes a recirculation line for recirculation of the partially consumed cathode gas from a junction point in the cathode gas outlet into a supply point in the cathode gas supply. Blocking apparatus is provided to block the cathode gas supply in the flow direction upstream of the supply point and to block the cathode gas outlet in the flow direction downstream from the junction point, such that a closed circuit for the partially consumed cathode gas is formed when the blocking apparatus is closed.
