PEFC Simulation Software Package P-Stack® - Concepts

Strategy for Fast Computation

Because internal phenomena in fuel cells are related to multiple physics aspects, computational costs for their simulation tend to be high using general CAE software. P-Stack® rapidly simulates the performance and internal states of full-scale fuel cells and stacks. A drastic reduction of computational costs is achieved by well-validated numerical models such as the MEA model, which reproduce measured I–V characteristics.

Well-Validated Reliable Numerical Model

Numerical models in P-Stack well reproduce not only the I–V curve but also various internal states. The figures on the right hand side present a comparison of the measured and calculated oxygen partial pressure distributions in a cathode channel under different utilization ratios UO2. The calculated results are in good agreement with the measured data for all UO2 cases. Oxygen is consumed almost constantly in low-UO2 condition, while a relatively faster consumption of oxygen is observed in the upper-flow region for UO2 = 80%. These behaviors are also well reproduced by P-Stack. These results indicate that the MEA model in P-Stack can quantitatively estimate oxygen consumption owing to the ORR reaction.
