Special Issue Information
Dear Colleagues,
The non-renewability of fossil fuels poses major energy challenges for humanity. Proton exchange membrane fuel cells (PEMFCs) are thought to be high-efficiency green energy sources. The proton conductor is a key component of such batteries. Nafion membranes are currently the most common type of commercial proton conductors. Although they have the advantages of high proton conductivity, superior mechanical and recycling qualities, high preparation cost and complexity, limited working conditions (60-80 C and high humidity required), and other faults, its widespread application is limited. The amorphous nature, in particular, limits researchers from learning more about the proton conduction process. Research centered around improving performance has found a bottleneck. Consequently, it is critical to create a novel class of inexpensive, crystalline, and highly proton-conductive replacement material. More significantly, the high crystallinity of these materials helps people understand the conductive mechanism better and can theoretically guide the development of high-proton-conductivity proton conductors, which has more practical utility. Therefore, the design and fabrication of proton-conducting MOFs, COFs, HOFs, and other porous materials have received considerable attention. In addition, these crystalline solid materials also show great application potential in other related fields, such as electrochemical synthesis, proton screening, sensors, battery ceramics, and REDOX flow batteries.
In this Special Issue, we welcome research articles or reviews centered around the research of proton conduction in crystalline materials, particularly the mechanism of proton transport in the framework. The related research will uncover the structure–activity relationship and precisely control the proton conductivity of crystalline materials, setting the groundwork for future practical applications.
Overall, this Special Issue will serve as a platform for researchers to exchange insights, present cutting-edge developments, and contribute to the advancement of proton conductive crystalline solid-state materials and their various applications in electrochemical related fields.
