Abstract The transition of a material from academia to industry is significant interest. Although extensive efforts have been devoted toward design and development various crystalline solid‐state proton conductors (SSPCs) such as MOFs/CPs, COFs, HOFs, POMs with impressive conductivity up 10 −2 – −1 S cm , less attention has paid verify their potentiality via membrane electrode assembly (MEA) construction for the usage in H 2 /O fuel cells, which ultimate goal R&D. Herein, we aim highlight MEA fabricated SSPCs validate reliability practicality cells. An in‐depth discussion comparison several industrially relevant parameters open circuit voltages, power density, current durability assessments along operating conditions key this contribution. Most importantly, ‘Critical Analysis’ section provides critical thoughts on so far developments performance four sorts materials pros cons, while identification existing issues future recommendations made ‘Future Prospects’ section, will be beneficial chemists getting sufficient new chemical insights interest engineers cell partners.

This work focuses on the design and development of membranes with constructive physicochemical electrochemical properties for fuel cell applications. Herein, novel electrolytes are prepared by blending sulfonated poly(1,4-phenylene ether sulfone) (sPEES) polyimide (PI). To improve ion-conducting properties, a zinc metal organic framework (Zn-MOF) is synthesized via solvothermal sonochemical methods. From XRD data, average crystallite size MOF found to be ∼27.8 nm. For preparation composites, Zn-MOF embedded in blend matrix, various synthesis parameters, such as reaction temperature, filler loading, casting time, were optimized. Among 3 wt % Zn-MOF-sPEES/PI membrane displays an ion-exchange capacity value 1.31 mEq/g, ionic conductivity 0.0811 S/cm at 80 °C, maximum peak power density 437 mW/cm2 voltage 0.72 V. In summary, experimental results affirm that well-suited applications hydrogen–oxygen cells.
