Simulación de una pila PEMFC "air-breathing" utilizando el código OpenFOAM

Weber, N.; Ferreira-Aparicio, P.; Chaparro, A.

The open-source CFD code OpenFOAM is being used to simulate the operation conditions of a proton exchange membrane fuel cell (PEMFC), with an 'air-breathing' cathode. The fuel cell operates with ambient air without additional convective elements. The anode works in dead-end mode using a static H2 pressure of 0.5bar, and with a hydrophilic membrane to allow for the evacuation of liquid water. This mode allows for 100% hydrogen consumption in the electrochemical reaction. This fuel cell type is being developed in CIEMAT and applied to small portable applications where extra weight and volume must be minimised, while maximizing hydrogen utilization. Being originally developed for solid oxide fuel cells, the openFuelCell model is extended to PEMFCs for the first time. It will provide basic knowledge of this special fuel cell configuration, essential characteristics of its performance reflected by the polarization curve, liquid water transport, temperature inhomogeneities, and heat transport.
