“…MOFs are crystalline solids built by the connection of metallic atoms and organic linkers yielding porous structures with cages, channels, or cavities, which have been considered as highly promising porous materials for a large variety of applications [ 106 , 107 ]. Up until now, more than 90,000 different MOF structures have been identified and their use in energy applications has blossomed in the last few decades [ 108 , 109 , 110 ]. MOFs have been used as efficient fillers with a wide variety of polymeric materials, including Nafion, SPEEK, and PBI, but also vinyl-type polymers, such as poly(vinylalcohol) (PVA) [ 111 , 112 , 113 ] and poly(vinylidene fluoride) (PVDF), [ 114 , 115 ] chitosan [ 116 ], and polyetherimide (PEI) [ 117 ].…”

The study of the electrochemical catalyst conversion of renewable electricity and carbon oxides into chemical fuels attracts a great deal of attention by different researchers. The main role of this process is in mitigating the worldwide energy crisis through a closed technological carbon cycle, where chemical fuels, such as hydrogen, are stored and reconverted to electricity via electrochemical reaction processes in fuel cells. The scientific community focuses its efforts on the development of high-performance polymeric membranes together with nanomaterials with high catalytic activity and stability in order to reduce the platinum group metal applied as a cathode to build stacks of proton exchange membrane fuel cells (PEMFCs) to work at low and moderate temperatures. The design of new conductive membranes and nanoparticles (NPs) whose morphology directly affects their catalytic properties is of utmost importance. Nanoparticle morphologies, like cubes, octahedrons, icosahedrons, bipyramids, plates, and polyhedrons, among others, are widely studied for catalysis applications. The recent progress around the high catalytic activity has focused on the stabilizing agents and their potential impact on nanomaterial synthesis to induce changes in the morphology of NPs.

“…High proton conductivity of about 4.1 × 10 −2 S.c006D −1 at 160 • C and RH = 0% has been reported by Anahidzade et al [75], who fabricated MIL-101 (Cr) by hydrothermal method followed by functionalizing it via the postgrafting route. However, restricted proton transportation caused by the grain boundary of MOFs resulted in decreasing the proton conductivity [76]. To overcome this issue, MOFs hybridization with other polymers can alleviate the low proton conductivity [77].…”

“…MOF‐carbons, composites of MOF metal nano‐particles, MOF‐polyoxometalates, MOF‐silica, and MOF‐organic polymers have been developed. MOF carbon composites, also known as carbon‐based materials and composites of the MOF, are very good because MOF itself is a material promised in various applications 68,111 .

Summary In this work, metal‐organic frameworks (MOFs), known as porous carbon, organic ligands, and crystalline materials have been reviewed as it consists of excellent properties, including high surface area, porosity, functional consistency, and uniform structure. The structural of MOFs, including secondary building units, open metal sites, pore sizes, functional materials, and development of MOF have been extensively studied as it helps to conduct electricity and promising good efficiency. To improve the performance in fuel cell applications, especially in catalytic activity such as oxygen reduction reaction and proton exchange membrane, the combination of MOF and other materials such as MOF/carbon material composites, MOF/metal nanoparticles (NPs), and MOF/biocomposites has been discussed in details, which can increase the potential and efficiency of catalysts. MOF‐derivatives, including MOF‐derived porous carbon, MOF‐derived NPs, MOF‐derived metal oxides, and MOF‐derived metal phosphide, has been provided in this review as it has its advantages; (a) increase the mass density of active sites, (b) increase intrinsic activity of active sites, (c) increase electrocatalyst conductivity (d), and accelerate electron transfer. Hence, it can produce materials with high thermal and chemical stability, embracing metal sites, and efficiency in active sites. These advantages have made the MOF a promising material to increase efficiency in fuel cell application and attract interest to further expand in other fields in the future.
