Introduction (Direct Methanol Cell)
Small Devices (e.g. golf carts, forklifts, electronic devices)
Used PET (Polyethylene) spacer properties (porousness)
Results
Thin and constant boundary layer despite velocity flux
Velocity Profile is relatively constant
Results (cont)
Permeability (ability of H2SO4 to pass) - significant
effects on pressure drop
Porosity (amount of open space), relatively minimal effects
Conclusion
Novelty in fluid flow modeling of a fluid electrolyte
Maximize size of pores (permeability)
Minimize size of channel (ohmic losses)
Maximize Volume Flux (methanol crossover)
Perhaps in research interest?
