REDUCED MODELLING OF PLANAR FUEL CELLS - ZHONGJ...

This book focuses on novel reduced cell and stack models for proton exchange membrane fuel
cells (PEMFCs) and planar solid oxide fuel cells (P-SOFCs) that serve to reduce the
computational cost by two orders of magnitude or more with desired numerical accuracy  while
capturing both the average properties and the variability of the dependent variables in the 3D
counterparts. The information provided can also be applied to other kinds of plate-type fuel
cells whose flow fields consist of parallel plain channels separated by solid ribs. These fast
and efficient models allow statistical sensitivity analysis for a sample size in the order of
1000 without prohibitive computational cost to be performed to investigate not only the
individual  but also the simultaneous effects of a group of varying geometrical  material  and
operational parameters. This provides important information for cell stack design  and to
illustrate this  Monte Carlo simulation of the reduced P-SOFC model is conducted at both the
single-cell and stack levels.
