The main objective of this study is to develop a Fuel cell system for electric vehicle purpose with minimum balance of plants (BOPs) to insure lesser parasitic losses and also compact design to replace IC engines. Though low temperature polymer electrolyte membrane fuel cell (PEMFC) has come up as a good contender for automotive application due to its quick start-up nature, it is associated with complex design and parasitic losses. But in the case of high temperature proton exchange membrane (HT PEM) the complexity involved in the design is minimized. The advantage of the present system based on phosphoric acid doped PBI (Polybenzimidazole) membrane is viz., (i) high tolerance to CO poisoning, (ii) no humidification complexity (iii) cooling of stack is easier. In the automotive application the major constrain is size so it becomes necessary to design a compact system. So far the serpentine design is considered to be the optimal as it has the advantage of uniform flow distribution though with higher pressure drop. Due to the higher pressure drop a pump is required to supply the oxidant for chemical reaction. But with lower pressure drop and fairly uniform flow distribution open cathode design was designed which facilitated the use of blower which had a lower power consumption. In the open cathode design the oxidant supply as well as the cooling was taken care using the blower.
