Abstract Proton exchange membranes with short-pathway through-plane orientated proton conductivity are highly desirable for use in membrane fuel cells. Magnetic field is utilized to create oriented structure membranes. Previously, this has only been carried out by nonconductive metal oxide-based fillers. Here, under a strong magnetic field, proton-conducting paramagnetic complex based on ferrocyanide-coordinated polymer and phosphotungstic acid used prepare composite conductive...
The two‐dimensional lamellar materials disperse platinum sites and minimize noble‐metal usage for fuel cells, while mass transport resistance at the stacked layers spurs device failure with a significant performance decline in membrane electrode assembly (MEA). Herein, we implant porous rigid sulfonated covalent organic frameworks (COF) into graphene‐based catalytic layer construction of steric mass‐charge channels, which highly facilitates activity oxygen reduction reactions both rotating...
Aligned nano-sponges accommodate only non-freezable water and facilitate efficient retention in the membrane, even under low relative humidity conditions.
The degradation of the membrane electrode assembly, originating from microstructural changes in catalyst layer, inhibits commercialization polymer electrolyte fuel cell. In particular, relative humidity during starting/working conditions cause crack growth and propagation within but reason is still not clear. Here, accelerated stress tests are designed starting (25 °C, 45% RH) to working with different RHs (20%, 99%) at 85 °C for cycles. For low RH 20%, no obvious change can be observed,...
