Abstract
An exhaust system for a fuel cell vehicle that is made of plastic. An inner surface of flow pipes that are part of the exhaust system are coated with a conductive material. A conductive through bolt extends through the pipes to be electrically coupled to the conductive coating and chasse ground of the vehicle so that any electro-static charge build-up as a result of the flow of water vapor and exhaust gas through the pipe will be dissipated.
