This study aims to analyze the effect of an evaporator in a fuel cell system which uses oxygen as a fuel. The oxygen from a liquid storage tank flows to the evaporator in order to supply gaseous oxygen fuel to the fuel cell stack. The design of the evaporator has an effect on the temperature and mass flow rate of the gaseous oxygen being supplied to the stack, which results in a change in the performance of the fuel cell system. In order to evaluate the characteristics, several components such as an oxygen storage tank, evaporator, stack, etc. were modeled and the parameters of the evaporator simulated. Increasing the heat exchange area in an evaporator enhances the effect of heat transfer, but its cost and overheated supplying oxygen gas may have a negative effect on the performance of the system. It is important to evaluate the optimization of the evaporator in a fuel cell system to ensure the better performance of the system.

Two thermodynamic power cycles are analytically examined for future engineering feasibility. These power cycles use a hydrogen-oxygen fuel cell for electrical energy production and use the thermal dissociation of water for regeneration of the hydrogen and oxygen. The first cycle uses a thermal energy input at over 2000K to thermally dissociate the water. The second cycle dissociates the water using an electrolyzer operating at high temperature (1300K) which receives both thermal and electrical energy as inputs. The results show that while the processes and devices of the 2000K thermal system exceed current technology limits, the high temperature electrolyzer system appears to be a state-of-the-art technology development, with the requirements for very high electrolyzer and fuel cell efficiencies seen as determining the feasibility of this system.
