Emissions Comparison Using a Clean Urban Bus Fleet

The objectives of this paper are to show the design and definition of a clean electric fuel cell prototype bus for urban transportation to operate in regular service in a local urban bus line, the hydrogen refuelling station to feed these clean buses and the environmental impact at the city of Zaragoza (Spain) due to this implementation. The source of the power is given by a fuel cell, different to the traditional diesel motorizations. Clean technologies are defined as those from production to the end of its usable life, passing by its use phase period and therefore including the recycling of parts and recovering of residues that does not affect the environment.
