Efficiency of all energy conversion devices like Fuel Cells
depend on efficient management of all energies arising from the kinetics of the
constituting fluids and adequate capturing of the detail of solid-fluid
interactions. Unlike flows
in macroscopic devices, complexity in the analysis of microflows varies with the
configuration and kinetics.
Apart from the problem of water-flooding at the cathode side of the PEM Fuel
Cell, inadequate analysis of the exchange of energies at the near-wall of the
enclosing channels constitute unresolved thermal mismanagement. Slip-flow irreversibility studies
based on Second Law of Thermodynamics in microchannels
have been undertaken. In this area of research, application of existing
microfluidic models to the design of thermal efficient fuel cells and other
energy conversion devices is proposed. Few of relevant publications in this area
include:
