Metal–organic frameworks in proton-exchange membrane for intermediate-to-high-temperature fuel-cell applications: a review

A proton-exchange membrane (PEM) is a vital component in fuel cells as a solid electrolyte that conducts ions. The high cost and degradation of Nafion® membrane in low-temperature fuel cells limits the technology’s commercialization. The development of intermediate (IT-PEMFCs) to high-temperature (H...
