LTNE approach to simulate temperature of cathode in a PEMFC

Summary, in English

The solid phase and fluid phase temperature and species distribution have been calculated numerically in this study. The model considered here consists of catalyst layer, porous-transport layer and the current collector region (rib). Two energy equations approach has been employed in the porous transport layer and one energy equation is solved for the catalyst layer to simulate the temperature distribution. Full multi-component diffusion model and Knudsen effect have been included for the simulation of the species distribution in both catalyst and porous-transport layer. The agglomerate model has been used to simulate the catalyst layer. It has been found that the diffusion coefficient is low in the catalyst layer due to low permeability and porosity causing stagnation zones and the temperature rise is maximum in the stagnation zones causing local hot spots.
