Metal Organic Frameworks Modified Proton Exchange Membranes for Fuel Cells

Abstract: Proton exchange membrane fuel cells (PEMFCs) have received considerable interest due to their low operating temperature and high energy conversion rate. However, their practical implement suffers from significant performance challenge. In particular, proton exchange membrane (PEM) as the core component of PEMFCs, have shown a strong correlation between its properties (e.g., proton conductivity, dimensional stability) and the performance of fuel cells. Metal-organic frameworks (MOFs) as porous inorganic-organic… Show more

“…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 ].…”

“…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 . Therefore, 111 reviewed that incorporated MOFs with carbon‐based materials consists of strong stability and another important feature is that it has high electrical conductivity.…”
