A New Concept for High-Performance Fuel Cell Design with Controlled Component Mixing using Jet Flow

A new concept is proposed for a high-performance fuel cell design. The concept is based on the intensification of mass transfer processes due to implementing multiple contact zones with jet flow and preventing the intermixing of the reactants and products. A proof of concept was performed by comparing the new fuel cell design with conventional proton-exchange membrane fuel cell (PEMFC) containing a standard membrane electrode assembly (MEA) and gas diffusion layer (GDL). It is shown that the application of the new concept for flow-field design provides an increase of the fuel cell performance of up to 40% without humidification and flooding problems.
