Gas diffusion layers Gas diffusion layers (GDLs) perform the significant functions in the proton exchange membrane fuel cells (PEMFCs), such as maintaining the water balance in the membrane electrode assem-bly (MEA) by allowing appropriate amount of water to move in and out from the reaction zone, providing the mechanical sup-port for the MEA and electrical contact between the electrodes and the current collectors. The key characteristics of [...]

Development of new catalysts for PEMFC As a versatile energy generation technology to effectively meet the stringent environmental norms, polymer electrolyte membrane fuel cells (PEMFCs) have gained significant attentionin the last few decades. Technically, among various alternate energy sources, PEMFCs have been considered as ideal systemsto serve as power sources for both stationary and mobile applications. To improve the commercial viability and customer acceptance, there are wide [...]

Fuel Cell With Nafion And Platinum The energy systems of our world obtain their energyrequirements mostly from fuel sources of fossil origin.Since these fuel sources of fossil origin have negativeenvironmental effects and are depletable, studies directedto the utility and production of clean and renewable energyresources that can be substituted for fossil originated fuelsand development of different energy systems are beingdemonstrated for a couple of decades. PEMFCs, whichare [...]

GDE Hot Pressing Membrane Electrode GDE Hot Pressing Membrane Electrode - Membrane Electrode Coating The first generation of MEA preparation technology adopts the hot pressing method to press the CL-coated cathode and anode GDL on both sides of the PEM to obtain MEA. This MEA is called a "GDE" structure. The preparation process of GDE-type MEA is relatively simple. Because the catalyst is coated on GDL, it is [...]

PEM Fuel Cell Proton exchange membrane fuel cell (proton exchange membrane fuel cell, PEM fuel cell or PEMFC for short) The PEM fuel cell contains a membrane electrode assembly (membrane electrode assembly, MEA for short), which is composed of a gas diffusion layer, electrodes and polymer electrolyte membranes. An electrochemical reaction takes place in the MEA to generate electricity. Membrane electrode is the place of multiphase material transport [...]
