A key Fuel Cell component: the Gas Diffusion Media

The heart of the Polymer Electrolyte Membrane Fuel Cell (PEMFC) is the Membrane Electrode Assembly (MEA), which consists of a proton exchange membrane (typically a perfluorosulfonated polymer) and two catalyst layers (i.e. anode and cathode). However, between the Bipolar Plate (BP) and the MEA it is common practice to insert a third component, the so-called [...]

WHAT is a fuel cell?

A Fuel Cell is an electrochemical device that continuously converts the chemical energy of the fuel (hydrogen) and an oxidant to DC electrical energy, heat and other reaction product (water). This reaction occurs inside the Membrane Electrode Assembly (MEA), an electrolyte membrane sandwiched between two gas diffusion electrodes.   Proton Exchange Membrane Fuel Cells (PEMFCs) [...]

Electrocatalytic corrosion of carbon support in PEMFC and durability enhancement strategies

Polymer electrolyte membrane fuel cell is the most appropriate power source candidate for the next-generation electric vehicle and small-scale stationary power. In recent years, durability has been one of the most important issues to be solved before the commercialization of PEMFCs. PEMFC performance loss under steady-state and cycling conditions has been attributed to the significant [...]
