Decoupling polymer, water and ion transport dynamics in ion-selective membranes for fuel cell applications

Research on Energy and Economics of Self-Made Catalyst-Coated Membrane for Fuel Cell under Different Oxidants

“…From the perspective of economics, the average performance of air and oxygen under long-time load is 1.2 V-10 A-12 W and 1.2 V-20 A-24 W. Referring to formula (7), the oxygen consumption per minute is as follows: P = 20 × 3 × 2 × 3.5 = 420 mL/min (10) According to the conversion, the oxygen consumption per hour is 0.0252 m 3 /h, and based on the power conversion relationship above, the power required to produce 0.0252 m 3 of oxygen is 8.82 W. Therefore, the net increase in power is as follows: This shows that under a long-time constant voltage operation, oxygen achieves a net power increase of 3.18 W/12 W = 26.5% compared with air.…”

“…Polymer membranes composed of MEA and GDL are the core structure of fuel cells and play a decisive role in cell performance, and this is also a key research field of global research [9][10][11][12][13][14]. Fabrizia Foglia [10] et al, studied the dynamic process of ion conduction in polymer membranes, discussed the serial decoupling approach, and improved the performance of MEA through system optimization.…”

Zimo Wang [11] et al, improved the comprehensive performance of MEA (the dispersion, mechanical properties, proton conductivities, swelling ratios, and water uptake), through modification and functionalization of the metal organic frameworks (MOFs) in polymer membranes.…”

In situ investigation of ion exchange membranes reveals that ion transfer in hybrid liquid/gas electrolyzers is mediated by diffusion, not electromigration

“…16,17 Although these studies provide valuable information about the membrane near-surface chemical composition, the ultra-high vacuum (UHV) conditions in which they are usually carried out do not necessarily reect the membrane chemical composition and its evolution under relevant operating conditions. Indeed, properties such as mechanical/chemical stability 18 and ionic conductivity [19][20][21] are closely linked to the hydration level and chemical environment in which the membranes operate. 22 Recently, different types of polymer membranes were investigated at near-ambient conditions using different spectroscopy methods, 23,24 including ambient pressure hard X-ray photoelectron spectroscopy (AP-HAXPES).…”

Synthesis and study of enhanced electrochemical properties of NiO nanoparticles deposited on TiO2 nanotubes

“…Nonetheless, anti-electrolytes based fuel cells modules have many extensions since energy units dependent on acidic electrolytes work principally with Pt-based catalysts and this reliance makes them more costly. [22][23][24][25][26][27][28] Anyway, the AFCs can work with moderately more affordable metals, for example, Au, Ag, and Ni. There are many benefits related to the AFCs, which make them more practical to make than acidic electrolytes-based energy fuel cells.…”
