  "textContent": "The invention provides a hydrogen sensing device 100, 100A capable of preventing sensor sensitivity decreases. [0002] A hydrogen sensor 150 detects the hydrogen in an exhaust pipe EP 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 SiOcapturing material 140 is placed between the siloxane decomposing material 130 and the hydrogen sensor 150, so that the SiOcapturing material can capture the SiOresulting from the decomposition of siloxanes by the siloxane decomposing material 130.",
