Engineering modelling of large-scale liquid fed direct methanol fuel cells stacks

摘要

Galvanostatic polarisation data for a small and a large scale direct methanol fuel cells are given.results from a flow visualisation study of the DMFC are used to highlight problems of gas management.issues on effective manifold design and the effect of operating ocnditions for the anode side gas management are discussed.Thermal.flow distribution and pressure drop modelling is used to predict stack performance under variabel operating conditions.Themperature profiles,pressure losses and flow maldistribution across the stack are addressed.
