Reviews on proton membrane materials for metal-organic frameworks in fuel cells

Abstract

Abstract:

A proton exchange membrane fuel cell（PEMFC） is a clean and efficient energy conversion device. Proton exchange membrane,as an important component of a PEMFC, can selectively permit the transfer of protons. However, high cost and poor stability against high temperature of proton exchange membranes restrict their practical applications in wide temperature range. Metal organic framework （MOF） materials are widely applied in catalytic and adsorption fields due to their facile synthesis, robust structures and high specific surface areas. In recent years, it has been revealed that a few MOF materials with high proton conductivity and low cost are deemed as potential alternatives for proton exchange membranes. Herein, the synthesis, chemical stability, proton conductivity and mechanism of MOF materials are discussed based on organic ligands （carboxylate, phosphonate, sulfonate, etc.） and guest molecules （imidazole, ammonium ion, etc.）. The development prospect, future challenges and feasible strategies of the conductive MOF materials are also proposed.

Key words: metal organic frameworks, fuel cell, proton conduction, organic ligand, guest molecule, stability
