Mass Transfer in Fuel Cells

Typical temperature distribution in a tri-layer cell with adjacent gas flow stream. [Pg.237]

There is a close similarity between heat and mass transfer in terms of transport rate equation and transport conservation equation. The diffusion and convective mass transfer modes are similar to the conduction and convection modes of heat transfer. Both diffusion and convection mass transfer play a significant role in the transport of reactant gas species through the gas flow channels and gas diffusion layers/electrodes. [Pg.237]

A brief description of these basic mass transport modes is given along with the mass transport rate and species mass conservation equations in the following sections. [Pg.238]
