Abstract
In the past decade, proton exchange membrane fuel cells (PEMFCs) have attracted much attention as emission-free power sources with high energy conversion efficiency. As one of the core components of PEMFCs, proton exchange membranes (PEMs) directly correlate with the performance of PEMFCs. However, there are few PEMs that fulfill the requirements for large-scale applications of PEMFCs. The organic-inorganic hybrid membranes possess advantages of both organic and inorganic phases and are considered to be promising PEMs in the PEMFC applications. In this review, we primarily focus on the most recent developments of Nafion-based and other polymer-based organic-inorganic hybrid membranes for PEMFCs. In addition, we also summarize some challenges that emerge during the preparation of the organic-inorganic hybrid membranes and propose approaches for overcoming these challenges.
Keywords: Nafion, organic-inorganic hybrid membrane, proton conductivity, proton exchange membrane fuel cell.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
