“…Nitrogen is considered to be an essential component for the formation of an active site in the catalyst for ORR. 6,[12][13][14][19][20][21][22] Several studies have reported the performance of the single DMFC operation utilizing the Fe-and Co-based catalysts as the cathode. One is the two-electron transfer pathway resulting in the H 2 O 2 production, whereas the other is the four-electron transfer pathway, which directly produces H 2 O.…”

Summary The application of nonprecious metal catalysts, such as iron (Fe) and cobalt (Co) catalyst, to direct liquid fuel cells (DLFCs), especially in direct methanol fuel cells, has been widely investigated. However, the application of such non‐Pt catalysts as cathode catalysts in direct formic acid fuel cell (DFAFC) operations has not yet been investigated. This study intends to evaluate the formic acid tolerance of such catalysts in case of oxygen reduction reaction. In addition, we investigate their performances in DFAFC using the Fe‐ and Co‐nitrogen‐doped carbon nanotubes (Fe‐NCNT and Co‐NCNT) as the cathode catalysts and compare these performances with the commercial Pt/C catalyst. Herein, Fe‐NCNT and Co‐NCNT were synthesized using the conventional method by the pyrolysis of the multiwalled carbon nanotubes, dicyandiamide, and metal salt under the flow of N2 at 800°C. Both the Fe‐NCNT and Co‐NCNT catalysts exhibit higher formic acid tolerance when compared with that exhibited by the Pt/C catalyst. Further, single‐cell tests with hydrogen‐fed polymer electrolyte fuel cell (PEFC) and DFAFC operations were conducted under various operating conditions to compare the performances of the cells while using the prepared catalysts and the conventional Pt/C catalyst. The PEFC performances in both the Fe‐NCNT and Co‐NCNT catalysts were significantly low (94.9mW cm−2 for Fe‐NCNT and 164.0 mW cm−2 for Co‐NCNT at 60°C). Regardless, the Co‐NCNT catalyst exhibited a maximum power density of 160.7 mW cm−2 in DFAFC operated at 60°C and7‐M formic acid. This value is comparable with that for DFAFC with a Pt/C catalyst (128.9mW cm−2) and is considerably higher than that obtained for other DLFCs while using a non‐Pt catalyst. Therefore, the usage of a non‐Pt metal catalyst as the cathode catalyst is preferable in case of DFAFC.

“…As indicated in Figure C, in the presence of NaOH, the efficiency of DyFNRs‐PdNPs‐MWCNT catalyst‐based MEA was improved. According to the literature, the higher performance arises from an adequate source of OH − ions that is essential for oxidation of methanol and diminished anode over potential . The highest value of anodic current and power density in optimum concentration of CH 3 OH and NaOH were 18 mA cm −2 and 4.4 mWcm −2 , respectively.…”

Summary Fuel cells are a new type of batteries that produce electricity from a continuous source of alcohols as long as fuel is inserted. In this study, decorated palladium nanoparticles (PdNPs) on dysprosium fluoride (DyF3) nanorods (DyFNRs)‐multiwalled carbon nanotubes (MWCNTs) were used for electrooxidation of methanol. DyFNRs were synthesized by the hydrothermal method, and the proposed multifunctional catalyst (DyFNRs/MWCNT‐PdNPs) was identified by several methods such as X‐ray diffraction, elemental mapping images, field emission scanning electron microscopy, energy dispersive analysis of X‐rays, and transmission electron microscopy which demonstrated a uniform distribution and high dispersion of the PdNPs on the supports. The electrocatalytic activity toward methanol electrooxidation on glassy carbon electrode (GCE) with DyFNRs/MWCNT‐PdNPs (DyFNRs/MWCNT‐PdNPs/GCE) was investigated by cyclic voltammetry (CV) and chronoamperometry (CA). Experimental results showed a high improvement in oxidation potential and peak current of methanol electrooxidation by DyFNRs/MWCNT‐PdNPs in comparison to DyFNRs and PdNPs. The values of the catalytic rate constant (k) and physical dimension (Ds) for methanol oxidation on the DyFNRs/MWCNT‐PdNPs/GCE catalyst were calculated 0.008 s−1 and 1.43, respectively. Moreover, the order of reaction was determined to be 0.43 and 0.13 for CH3OH and NaOH, repectively. Finally, the synthesized catalyst was evaluated in direct methanol fuel cell (DMFC). The single DMFC with proposed anodic catalyst, DyFNRs/MWCNT‐PdNPs, indicated a power density of 4.4 mW·cm−2 at a current density of 18 mA·cm−2 in alcohol (1 M) and NaOH (1 M).

“…As shown in Figure (C) In the presence of NaOH, Fe 3 O 4 HNS‐PdPtAuNPs catalyst based MEA demonstrated improved performance. As illustrated in the literature, this enhancement in efficiency could be related to enough supply of OH − ions required for methanol oxidation and reduced anode overpotential . The maximum current density and peak power density for 1 M methanol and 1 M NaOH were 34 mA cm −2 and 5.44 mW cm −2 , respectively.…”
