Proton Exchange Membrane Fuel Cells

2012
Abstract Proton-exchange membrane fuel cells are promising devices for a variety of energy-conversion technologies. However, they have limited market penetration due to their high cost, which stems from the need to balance durability, performance, and materials.

Tailoring FeN4 Sites with Edge Enrichment for Boosted Oxygen Reduction Performance in Proton Exchange Membrane Fuel Cell

Advanced Energy Materials, 2019
Transition metal atoms with corresponding nitrogen coordination are widely proposed as catalytic centers for the oxygen reduction reaction (ORR) in metal–nitrogen–carbon (M–N–C) catalysts.

New Anhydrous Proton Exchange Membrane for Intermediate Temperature Proton Exchange Membrane Fuel Cells

ChemPhysChem, 2011
AbstractHerein, we study the preparation and characterization of a new kind of proton exchange membrane. In the proton‐conducting membrane of poly(vinylidene fluoride) (PVDF)/poly(ethylene oxide) (PEO)/dodecyl benzenesulfonic acid (DBS‐H), we use PEO as “proton solvent” due to its flexible molecular chain.

Proton Exchange Membrane Fuel Cells (PEMFCs)

2020
Membrane electrode assembly (MEA) is the core component of proton exchange membrane fuel cell, which is composed of proton exchange membrane, cathode and anode catalytic layers and gas diffusion layers. The cost of MEA accounts for more than 60% of that of the total system, and particularly, the cost of platinum (Pt) catalysts accounts for nearly 70 ...

Data-Fusion Prognostics of Proton Exchange Membrane Fuel Cell Degradation

IEEE transactions on industry applications, 2019
Proton exchange membrane fuel cell (PEMFC) degradation prediction is essential especially in transportation applications, since one of the major issues that hinder its worldwide commercialization is represented by its durability.

Proton exchange membrane fuel cell development

Proceedings of the 24th Intersociety Energy Conversion Engineering Conference, 2003
A description is given of a prototype proton exchange membrane fuel cell for high-energy-density power supplies in the 1-100 kW range that has been designed, built and tested. A closed-loop fuel cell system for use in an autonomous underwater vehicle is also described.

Integrating PGM‐Free Catalysts into Catalyst Layers and Proton Exchange Membrane Fuel Cell Devices

Advances in Materials, 2019
While proton exchange membrane fuel cells (PEMFCs) continue to expand into commercial markets, there is still pressure to decrease cost. One of the largest opportunities to reducing cost is to reduce the amount of platinum‐group metal (PGM) catalysts ...

Proton-exchange membrane regenerative fuel cells

Journal of Power Sources, 1994
Abstract This paper will update the progress in developing electrocatalyst systems and electrode structures primarily for the positive electrode of single-unit solid polymer proton-exchange membrane (PEM) regenerative fuel cells. The work was done with DuPont Nafion 117 in complete fuel cells (40 cm2 electrodes).
