초록

An exhaust gas exhausted from a fuel cell is sent to a silencer through an exhaust pipe. The silencer is provided with a conductive noise absorbing material, and is fixed to a vehicle body through a metallic fixing jig. Thus, the noise absorbing material is earthed to the vehicle body so that it is possible to prevent static electricity from being generated in the use of the fuel cell vehicle such as in a low humidity environment.

청구항

What is claimed is: 1. A fuel cell vehicle comprising: a vehicle body; a fuel cell for generating an electric power through an electrochemical reaction between a fuel gas and an oxidizer gas; an exhaust pipe for exhausting an exhaust gas exhausted from the fuel cell; and a silencer in communication with the exhaust pipe for reducing an exhaust noise due to the exhaust gas, the silencer and the vehicle body are fixed by a conductive fixing jig, wherein the silencer comprises: a silencer body; an inner pipe provided within the silencer body; a noise absor...
