Journal ArticleDOI
Two-Phase Dynamic Modeling of PEMFCs and Simulation of Cyclo-Voltammograms
TL;DR: In this paper, a mathematical model is developed that is based on a coupled system of partial differential equations, containing a dynamic and two-phase description of the proton exchange membrane fuel cell (PEMFC) and a membrane model that accounts for Schroeder's paradox.
Journal ArticleDOI
Control of miniature proton exchange membrane fuel cells based on fuzzy logic
TL;DR: In this article, a control strategy for miniature hydrogen/air proton exchange membrane (PEM) fuel cells is presented based on process modelling using fuzzy logic and tested using a PEM stack consisting of 15 cells with parallel channels on the cathode side and a meander-shaped flow-field on the anode side.
Journal ArticleDOI
Microstructure-property relationships in a gas diffusion layer (GDL) for Polymer Electrolyte Fuel Cells, Part I: effect of compression and anisotropy of dry GDL
Lorenz Holzer,Omar Pecho,Jürgen Schumacher,Philip Marmet,Ole Stenzel,Felix N. Büchi,Adrien Lamibrac,Beat Münch +7 more
TL;DR: In this article, new quantitative relationships are established between effective properties (gas diffusivity, permeability and electrical conductivity) for a dry GDL (25 BA) from SGL Carbon with the corresponding microstructure characteristics from 3D analysis.
Journal ArticleDOI
Free open reference implementation of a two-phase PEM fuel cell model
Roman Vetter,Jürgen Schumacher +1 more
TL;DR: The first open standalone implementation of a full-blown, steady-state, non-isothermal, two-phase model for low-temperature PEM fuel cells is published, based on macro-homogeneous modeling approaches and implements the most essential through-plane transport processes in a five-layer MEA.
