“…Slight loss of AEMFC performance for FeNiNÀ MC can be due to the various factors including AEM, morphology of catalysts, water management, etc. [65,66] The AEMFC performance of FeNiNÀ MWCNT and FeNiNÀ MC is comparable to the reported transition metal-nitrogen doped carbon materials using similar operating conditions (Table S5). The comparison of AEMFCs performance is complicated due to varying operating conditions and different AEM used in literature.…”

Iron and Nickel Phthalocyanine‐Modified Nanocarbon Materials as Cathode Catalysts for Anion‐Exchange Membrane Fuel Cells and Zinc‐Air Batteries**

Iron and nickel phthalocyanines along with different carbon supports, i. e., multi‐walled carbon nanotubes (MWCNT), graphene, carbide‐derived carbon, Vulcan carbon, and mesoporous carbon (MC, from Pajarito Powder, LLC), are used to prepare six bimetallic (Fe, Ni) N‐doped carbon‐based catalysts. The aim of this work is to investigate the electrocatalytic activity of bimetal phthalocyanine‐modified nanocarbon catalysts, e. g., the effect of carbon supports on the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), including the anion‐exchange membrane fuel cell (AEMFC) and rechargeable zinc‐air battery (RZAB) configuration. The catalysts exhibit excellent electrocatalytic activity as exemplified by their half‐wave potential (E1/2) for ORR and the potential at which the OER current density reaches 10 mA cm−2 (Ej=10), but the best performing catalysts are FeNiN−MC (E1/2=0.88 V, Ej=10=1.58 V) and FeNiN−MWCNT (E1/2=0.87 V, Ej=10=1.59 V). In AEMFC analyses, FeNiN−MWCNT cathode provides peak power density (Pmax) of 406 mW cm−2, slightly higher than that of FeNiN−MC (Pmax=386 mW cm−2). Both catalysts exhibit a good RZAB performance (Pmax of 85 mW cm−2 for FeNiN−MWCNT). The assembled RZABs run stably for 48 h without any significant loss of performance.

“…Also, the high thickness of the NPMC catalyst layer at the cathode and water management issues (e.g. flooding or drying) have a great influence on the overall fuel cell performance [42,43]. Considering these aspects together with different GDL material and gas flow rates can provide a possible explanation for the high Pmax of 415 mW cm −2 obtained with FeCoNC-at catalyst in an earlier investigation, where otherwise similar conditions to the present study were used [44].…”

The use of Pt-based cathode catalyst materials hinders the widespread application of anion exchange membrane fuel cells (AEMFCs). Herein, we present a non-precious metal catalyst (NPMC) material based on pyrolysed Fe and Co co-doped electrospun carbon nanofibres (CNFs). The prepared materials are studied as oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalysts in alkaline and acidic environments. High activity towards the ORR in alkaline solution indicated the suitability of the prepared NPMCs for the application at the AEMFC cathode. In the AEMFC test, the membrane-electrode assembly bearing a cathode with the nanofibre-based catalyst prepared with the ionic liquid (IL) (Fe/Co/IL-CNF-800b) showed the maximum power density (Pmax) of 195 mW cm −2 , which is 78 % of the Pmax obtained with a commercial Pt/C cathode catalyst. Such high ORR

“…Apart from synthesis, enhanced activity and stability studies of PGM‐free catalyst are main focus of future research. Low active sites density leads to high catalytic loading, due to which electrode thickness increases and electrode porosity decreases, which can ultimately impart mass transport issues to the cells 105,106 . Secondly, nature of chemical bonding and physical interaction between PGM‐free catalyst active sites can impart them tendency of degradation of active sites like local corrosion or poisoning 107 .…”

Summary The declining reserves and environmental concerns related to the use of fossil fuels have made the global think tanks to pursue for the technologies considered to be renewable as well as sustainable. Fuel cell technology is emerging and a green way to produce electricity, provided sufficient amount of hydrogen (fuel) is available that directly convert chemical energy to electrical energy. Despite of being an efficient and eco‐friendly source of energy, commercialization of fuel cells is still difficult to attain. Techno‐economic challenges like high manufacturing and assembly costs, water management, system size, nondurability, and instability of the system need to be addressed. In order to resolve these issues, considerable research has been carried out for the development of novel and inexpensive materials for the fuel cells. In this article, we have reviewed the development of electrodes and electrolyte materials for different types of fuel cells. A detailed description of applications, challenges, and improvement of electrodes/electrolytes materials of different types of fuel cells (polymer electrolyte membrane fuel cells, direct methanol fuel cells and solid oxide fuel cells) have been reported in this review article. A brief review of the development of materials for electrode of molten carbonate fuel cells has also been presented in the review.
