“…As a representative technology for hydrogen conversion, anion exchange membrane fuel cells (AEMFCs) have achieved growing attention due to the accessibility of using non-noble metal-based catalysts for the oxygen reduction reaction (ORR) with platinum (Pt)-like performance at the cathode. 1–3 Nevertheless, the anodic hydrogen oxidation reaction (HOR) still suffers from relatively sluggish kinetics in alkaline electrolytes, where the catalytic performance, even for the Pt-group metals, is two orders of magnitude lower than that in acidic electrolytes. 4–6 To promote the commercialization of AEMFCs, it is becoming highly attractive to develop high-activity catalysts based on non-noble metals for the alkaline HOR.…”

“…Furthermore, the overall highest P max value for AEMFC achieving 3.4 W cm −2 has been also recorded with Pt/C catalyst according to the literature [55] . The common feature for these excellent AEMFC results is the use of ETFE‐based membrane in the membrane‐electrode assembly (MEA) setup [53–56] . This confirms the fact that the effective integration of catalyst with the AEM and the properties of AEM play at least as crucial role in the AEMFC performance as the ORR activity of the electrocatalysts [57] .…”

“…Recently, P max of 2 W cm −2 was reported for Fe−N−C cathode catalyst by Adabi et al. The AEMFC performance of Fe−N−C based catalyst is reported to be lower than commercial Pt/C‐based catalysts ( P max value of 2.6 W cm −2 ) [54] . Furthermore, the overall highest P max value for AEMFC achieving 3.4 W cm −2 has been also recorded with Pt/C catalyst according to the literature [55] .…”

The development of non-precious metal cathode catalysts for anion exchange membrane fuel cells (AEMFC) is beneficial for achieving a more affordable and sustainable H 2 economy. Herein, we propose a polypyrrole, polythiophene, and multiwalled carbon nanotube-based composite material (PPy/PTh/ MWCNT) for the electrocatalysis of oxygen reduction reaction (ORR) at the AEMFC cathode. The PPy/PTh/MWCNT catalyst has a tubular micro-mesoporous structure with high specific surface area. The elemental composition of the catalyst's surface was studied by X-ray photoelectron spectroscopy. In 0.1 M KOH solution, the ORR half-wave potential is À 0.16 V (SCE) and the electron transfer number is 4. In a single-cell AEMFC, the PPy/ PTh/MWCNT catalyst exhibited a maximum power density of 284 mW cm À 2 , which is 86 % of the value obtained using commercial Pt/C cathode catalyst under the same testing conditions.

“…Converting renewable energy resources such as wind and solar energy into chemical fuels has been proposed as an efficient and carbon-neutral strategy. [1][2][3][4][5][6][7] Hydrogen, as the most promising candidate fuel, possesses a high energy density and generates zero emission during consumption. Thus far, hydrogen is still mainly prepared in the industry via methane reforming promoted by steam.…”

The desire to exploit clean and sustainable energy sources with high gravimetric energy density has greatly inspired the exploration of hydrogen energy as an affordable alternative to fossil energy. Electrocatalytic water splitting is an efficient method for the low‐cost production of pure H2, but the use of platinum (Pt)‐like active electrocatalysts for the hydrogen evolution reaction (HER) remains necessary. In attempts to replace high‐value, scarce Pt catalysts, nickel‐based materials are being developed, as earth‐abundant HER electrocatalysts. Recently, a number of advanced nickel (Ni)‐based catalysts have been developed by rational synthesis strategies, including morphology control, structure tailoring, and interface engineering, significantly improving the HER performance. This review summarizes recent achievements in the application of Ni‐based HER electrocatalysts and demonstrates the advantages of each category in enhancing the HER performance. The current progress in the theory of water evolution and various modern techniques for characterizing catalysts are also reviewed, along with the rational design of Ni‐based nanostructure catalysts. Finally, the challenges in the practical applications of Ni‐based HER catalysts are highlighted.
