To develop proton-exchange membranes with adequate performances at low RH, an attractive strategy consists of the incorporation of inorganic fillers into the host Nafion polymer. ...
Why is an activation procedure or break-in necessary for a membrane electrode assembly (MEA)? A large reason for performing an activation procedure or break-in is to properly humidify the membrane portion of the MEA that was dried out during the hot press stage of the membrane electrode ...
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 ...
Since current is defined as the flow of electrons (or protons) and a Hydrogen molecule is just 2 protons and 2 electrons, it follows that when you put a certain number of electrons across the membrane (current), it will generate an equivalent number of Hydrogen molecules. ...
The Catalyst layer can either be applied to the membrane (as in a 3-layer or Catalyst Coated Membrane (CCM)) or applied to the GDL material itself. ...
We used DEMS to investigate the mechanism of carbon support corrosion (CSC) in-situ at the cathode of proton exchange membrane fuel cell (PEMFC). The cathode exhaust gases were sampled with a Hiden Analytical QIC-20 mass spectrometer. ...
A membrane electrode assembly (MEA) for microbial fuel cells (MEA-MFC) was developed for continuous electricity production while treating domestic wastewater concurrently. ...
Membrane electrode assemblies are the key components of proton exchange membrane fuel cells. ...
The goal of the present study is the development and comparative characterisation of carbon-supported and nanostructured Pd- and Pt-based electrocatalysts for hydrogen oxidation in Proton Exchange Membrane (PEM) H2/O2(air) fuel cells and proton reduction in PEM water electrolysers. ...
