Sažetak
A MATLAB model was developed and used to study the steady and transient states of a fuel cell stack. A 1 kW air-cooled fuel cell stack, developed by Proton Energy Systems Inc., was used for this analysis. The analysis included stack mass and heat balance, heat transfer from the stack to cooling air and heat transfer to the surrounding air. Operation of the stack under various scenarios was simulated such as start-up from room temperature, steady state at full and half load and sudden changes of load (from full to half load), under constant or variable flow rate of cooling air. The results of these analyses and simulation show how the stack temperature changes in and between the steady states achieved at different loads and at different cooling air flow rates.
