This paper deals with system level analysis of a methanol fuel processor for an indirect hydrogen / air based fueI cell vehicle (FCV) with proton exchange membrane (PEM) fuel cell stack. This analysis focuses on the performance of the fuel processor from the viewpoint of efficiency and the requirements placed on it by the fuel cell vehicle. It is widely accepted that hydrogen supply is an important issue in PEM-FC vehicle systems. The lack of a well-entrenched hydrogen infrastructure and the nascent state of hydrogen storage technology has led to development of on-board hydrogen generation systems to meet the fuel cell hydrogen demand. The primary fuel is typically a hydrocarbon (methanol, gasoline) which is then 'reformed' in a fuel processor to generate the hydrogen needed by the fuel cell stack. A great deal of effort has been expended in developing fuel processors that would satisfy the rigorous demands of automotive applications. There are severe constraints concerning volume, weight, cost, response times, fuel reformate CO cleanup and efficiencies. Conventional fuel processor designs have proven to be unsuitable for FCV applications and recent developments have pointed the way towards some advanced fuel processor designs that have a better chance of meeting the challenges posed by FCV applications.
