摘 要：North American, European, and Asian automobile manufacturers project that commercial hydrogen fuel cell-powered light-duty road vehicles will be released by 2015 for general consumer applications. Initially they will be sold in select markets; a much broader market penetration is expected by 2025, when more than 1 million hydrogen fuel cell electric vehicles (FCEVs) are expected to be on the road in the United States. Significant infrastructure implementation, including production capacity, transport, storage, and dispensing, is ongoing to prepare for the commercial introduction of FCEVs. Even more critical for the release of commercial hydrogen vehicles in the United States is the establishment of the Federal Motor Vehicle Safety Standard (FMVSS) for hydrogen-powered vehicles. To ensure international harmony, North American, European, and Asian regulatory representatives are striving to base their respective national regulations on an international safety standard, the Global Technical Regulation (GTR), Hydrogen Fueled Vehicle, which is part of an international agreement pertaining to wheeled vehicles and associated equipment.
