In the present work, highly porous cobalt-based ZIFs are strung along the highly conducive CNT backbone by using a simple one-pot technique at room temperature, which is then utilized to derive a porous, corrosion-resistant, Co nanoparticle-embedded electrocatalyst. Herein, for the first time, the single cell performance of the Co-ZIF-67-derived electrocatalyst has been evaluated by fabricating membrane electrode assemblies of alkaline exchange membrane fuel cell (AEMFC) and zinc-air battery (ZAB) systems. A maximum power density of 296 mW/cm(2) (vs. 317 mW/cm(2) for 40 wt.% Pt/C) and 60 mW/cm(2) (vs. 64 mW/cm(2) for 40 wt.% Pt/C) in the single cells of ZAB and AEMFC systems, respectively, establishes the practical proficiency of the homemade electrocatalyst for cathode applications during realistic system-level validations.</p>10aBatteries10aCarbon nanotubes10aComposite materials10afuel cells10ametal-organic frameworks1 aAiyappa, Harshitha, Barike1 aBhange, Siddheshwar, N.1 aSivasankaran, Vijitha, P.1 aKurungot, Sreekumar  uhttps://library.ncl.res.in/content/single-cell-fabrication-towards-realistic-evaluation-cnt-strung-zif-derived-electrocatalyst
