The principles of the more important fuel cells are described and their current state of development assessed. Reference is made to the suitability of various fuels for fuel cell power systems applied to locomotive traction.
The overall scheme for a 300-kW power unit using a low-temperature fuel battery is described. While technically possible, such a system is unlikely to be economically viable. It is suggested that fuel cell traction for locomotives will have to await the development of an improved fuel cell, such as one using a solid oxide electrolyte.
