Characterisation of two-phase flow and its impact on the performance of a Polymer Electrolyte Membrane fuel cell stack
Water management is one of the most critical issues for high-performance Polymer Electrolyte Membrane (PEM) fuel cells. A flow network model was developed to study the possibility of two-phase flow inception along the gas flow channels in the cathode side of a PEM fuel cell stack. The conventional Darcy-Weisbach equation and homogeneous flow model are used to estimate the pressure distributions ...

Fuel cell–based distributed generation system with power flow and power quality control
This paper presents the modelling and control of fuel cell–based distributed generation system with embedded active filter functioning. It includes the modelling of proton electrolyte membrane fuel cell and the power conditioning unit interfacing the fuel cell to the utility grid with proper power flow control. The output of the fuel cell stack is given to the DC–DC boost converter ...

What is the Purpose of a Gas Diffusion Layer (GDL)?
The Gas Diffusion Layer (GDL) plays several critical roles in a typical fuel cell application and is often integrated as part of the Membrane Electrode Assembly (MEA). Typical applications that use GDLs consist of Polymer Electrolyte Fuel Cells (PEMFC) and Direct Methanol Fuel Cells (DMFC). When a GDL is coated with a catalyst it is than referred to as a Gas Diffusion Electrode (GDE), which are ...

Towards an European Fuel Cell Strategy
Head of Unit 'Energy Consumption Technology' At the onset of the Fourth Framework Programme for Community research and technological development including demonstration, a ten year fuel cell strategy for Europe was published in 1995 jointly by DG XII (Directorate General for Science, Research and Development) and DG XVII (Directorate General for Energy). The interest of the European Community ...
