Characterization techniques for gas diffusion layers for proton exchange membrane fuel cells – A review

Lattice Boltzmann Pore-Scale Investigation of Coupled Physical-electrochemical Processes in C/Pt and Non-Precious Metal Cathode Catalyst Layers in Proton Exchange Membrane Fuel Cells

“…Several technical barriers must be overcome before widespread commercialization of PEMFC technology. These barriers include high cost, material durability and water and heat management [1]. The utilization of precious metal-based catalysts, particularly platinum (Pt), contributes significantly to the cost of PEMFCs.…”

X-ray Tomographic Analysis of Porosity Distributions in Gas Diffusion Layers of Proton Exchange Membrane Fuel Cells

“…The proton exchange membrane fuel cell (PEMFC) has recently received significant attention from the automotive industry as a clean and efficient energy system with a significant potential for development and integration into transportation systems [1][2][3]. A PEMFC creates electrical power through the electrochemical reduction-oxidation reaction of a fuel and an oxidant.…”

“…Reactant gases are transported through a flow field in the bipolar plate to their respective electrodes of the MEA and are then diffused through the GDLs to the CLs, which is where the reduction-oxidation reaction occurs. The ineffective transport of reactants to, and removal of products from, the reaction sites on the CLs can lead to mass transport issues within the cell which, in turn, lead to decreased performance, especially in high power density regions [3,4].…”

“…This porous carbon layer is important for the electrical connection and heat dissipation between the CL and bipolar plate; while it also acts as a mechanical support for the MEA [3]. Another key process occurring in the GDL is the mitigation of the water produced at the cathode by the electrochemical reaction [6].…”

Effect of Thermal Annealing on Mechanical Properties of the Stainless Steel with TiCxNy Composites

“…It is well known that proton exchange membrane fuel cells have received broad attentions due to their low operation temperature, low emission and quick startup [1], [2]. This type of fuel cells is an electrochemical cell that is fed hydrogen, which is oxidized at the anode, and oxygen that is reduced at the cathode.…”
