Cheaper pipeline (per mile) costs compared to crude oil pipeline costs. Hydrogen can be extracted from water, and after extraction, it is combined in a fuel cell with oxygen to create H2o. Currently, many people advocate a hydrogen economy, which will use hydrogen as an energy carrier or fuel. Compared subsequently other people, considering someone always tries to set aside the . Although diesel fuel is considered to be more efficient because it converts heat into energy rather than sending the heat out the tailpipe as gas-powered vehicles do, it doesn't result in flashy high-speed performance. All that comes out of the exhaust pipe is water, which does no harm at all to the environment. Flex-fuel vehicles that can run on E85 fuel have found that their gas mileage rates are over 25% lower, with some models seeing a 30% reduction with city miles. High fuel costs. An advantage here is it can thus be on a lean fuel-air mixture. In essence the FCEV is firstly an electric car with a hydrogen fuel cell range extender added.
