Solaris hydrogen bus tested in Paris

The Urbino 12 hydrogen bus is an extremely technologically advanced vehicle that uses a set of fuel cells with a power of 70 kW to generate energy. The hydrogen supplied to the fuel cells is converted into electricity, which, in turn, is feeding directly the bus driveline which consists of an axle with electric engines. The bus is also fitted with a Solaris High Power battery acting as an additional electric power storage facility. The hydrogen is stored on the roof in five tanks of the latest generation available on the market. The sole products of the chemical reaction occurring in the fuel cell are heat and steam.
