A novel 2D nickel(ii) complex (1) has been successfully synthesized using a 2,2′-bipyridyl, polycarboxylsulfonate ligand H4SBTC and Ni2+ ions. Owing to the presence of abundant water molecules, hydrogen bond networks and other protons, 1 and its hybrid membranes demonstrate high proton conductivity.

Tremendous efforts are being made to produce polymer electrolyte membrane (PEM) for fuel cell using advanced materials in order to replace Nafion due to the high costs and its complicated synthesis procedures. One of the efforts include an extensive research on natural polymer to produce biopolymer based electrolyte membranes with desirable properties such as high proton conductivity, as well as good chemical and thermal stabilities. The examples of biopolymer that have been used are polysaccharide (e.g. cellulose, starch and glycogen), chitin and chitosan. This paper presents an overview of the types of biopolymer used to produce a PEM, comprised also their chemical and physical properties, and its performances in fuel cell applications.

Through cation substitution in a zirconium based coordination polymer, an isostructural framework 1@NH4+ has been prepared without any apparent structural change. The proton conductivity of 1@NH4+ is successfully improved. It exhibits high proton conductivity (1.39 × 10−2 S cm−1) at 98% relative humidity and 60 °C.
