Practical Fuel Processing - Mobile Applications

The preferred fuel for a fuel ceU is hydrogen. While there are applications in which hydrogen can be used directly, such as in space vehicles and local transport, in the foreseeable future, for other stationary and mobile applications, the choice of fuel and its conversion into hydrogen-rich gas are essential features of practical systems. The range of fuels and their processing for use in fuel cell systems are described in Chapter 8. Chapters 9 and 10 describe the mechanical and electrical components that make up the complete fuel cell plant for both stationary and mobile applications. 

Due to the high hydrogen storage capacity of the ammonia molecule (17.7 wt% equal to an energy density of 4,318 Wh kg 1), its decomposition is intensely investigated for COx-free hydrogen production for mobile fuel cell applications [146]. However, compared with the well-established Haber Bosch process for ammonia synthesis, its decomposition is underdeveloped and requires substantial improvements before it can be considered as a practical contribution to the energy supply toolbox.
