Another challenge is hydrogen's storage and transport due to its low volumetric energy density. These issues have elevated hydrogen carriers—particularly methanol—to a prominent position. Methanol's favorable H/C ratio, liquid state under ambient conditions, and renewable production potential establish it as a compelling hydrogen carrier. Already essential in vehicle fuels and chemical production, methanol's role is poised to expand further. Among conversion routes, methanol steam reforming (MSR) stands out for its high hydrogen yield and low CO production. This review outlines strategies for lowering the MSR reaction temperature, enabling integration with proton exchange membrane fuel cells (PEMFC), and leveraging the thermal synergy between the two systems. The review highlights the critical roles of catalysts and reactor design in optimizing MSR–PEMFC integration. A detailed evaluation of Cu-based and group 8–10 metal catalysts provides insight into their suitability for PEMFC applications. Reactor configurations, including conventional, membrane, and micro-channeled designs, are assessed for their integration potential.

Current drag reduction agents often worsen heat transfer performance. To overcome the contradiction between drag reduction and heat transfer deterioration, comb-type ternary block copolymers, hexadecyl methacrylate-co-dimethylaminoethyl methacrylate-co-methacrylic acid, have been designed and synthesized through photoinitiated polymerization and used as emulsifiers to prepare emulsified fuels. The emulsions with different compositions of JP-10 to water as 9.5:0.5, 9:1, 8.5:1.5, and 8:2, respectively, were characterized using creaming index analysis, dynamic light scattering and zeta potential measurements, rheological analysis, laser scanning confocal microscopy and polarized optical microscopy measurements, interfacial tension and interfacial film rheology measurements. A significant enhancement in heat sink and heat transfer coefficients of the emulsified fuel compared to pure JP-10 is observed within the temperature range from 100 to 225 °C. Simultaneous enhancements in drag reduction rate and heat transfer coefficient for the emulsified fuel in a distributed flow calorimeter can reach 19.5 % and 6.09 %, respectively.
