ELECTRIC TRANSPORT PROCESS FOR THE BULK OF A PEM FUEL CELL
(2017) 7th European Fuel Cell Piero Lunghi Conference, EFC 2017 In EFC 2017 - Proceedings of the 7th European Fuel Cell Piero Lunghi Conference p.71-72- Abstract
Performance of a proton exchange membrane (PEM) fuel cell is very sensitive to its electric resistance appearing in its functional components. In this paper, the electric resistance as well as related parameters of a cell is evaluated by a recently developed numerical method in the through-plane direction of the electrodes. The results show that the channel/rib structure leads to non-homogeneous electric field and current flow, especially within the region around the corner of bi-polar plates (BPP) close to the channel. In addition, the current below the channel flows across with a longer distance from the middle of the gas diffusion layer (GDL) to the BPP's shoulders. Finally, the electric resistance is predicted with 99.4 mΩ... (More)

In addition, the current below the channel flows across with a longer distance from the middle of the gas diffusion layer (GDL) to the BPP's shoulders. Finally, the electric resistance is predicted with 99.4 mΩ cm2 of the bulk of an entire cell for the studied case condition.
