Article Synopsis
- The study develops a detailed numerical model for a micro-planar proton-conducting solid oxide fuel cell that focuses on anode-supported fuel cells with methane reforming.
- The model incorporates several complex equations related to mass transfer, chemical reactions, and energy to predict how the fuel cell operates.
- Results indicate that adjusting the air-to-fuel ratio affects current and power density, with a specific improvement noted at an A/F ratio of 0.5; the artificial neural network used for predictions displays high accuracy.

Lanthanide metal-organic frameworks (LMOFs) have established themselves as promising proton-conducting materials among all types of porous coordination polymers and covalent organic frameworks. The structural diversity of LMOFs and high oxophilicity with a high coordination number of lanthanide ions make LMOFs a standout material for proton conduction. In the last few years, ample research efforts have been devoted to designing and developing proton-conducting lanthanide metal-organic frameworks (PCLMOFs).

Proton-conducting materials have attracted considerable interest because of their extensive application in energy storage and conversion devices. Among them, metal-organic frameworks (MOFs) present tremendous development potential and possibilities for constructing novel advanced proton conductors due to their special advantages in crystallinity, designability, and porosity. In particular, several special design strategies for the structure of MOFs have opened new doors for the advancement of MOF proton conductors, such as charged network construction, ligand functionalization, metal-center manipulation, defective engineering, guest molecule incorporation, and pore-space manipulation.

Article Synopsis
- * Researchers improve the stability of an imine-based covalent organic framework (CPOF-10) by converting it to a more stable amide-linked version (CPOF-11), which allows for better integration of liquid proton-conducting acids.
- * The findings show that CPOF-11 exhibits significantly enhanced proton conductivity compared to its precursor, achieving one of the lowest activation energy values reported for proton-conducting materials, indicating potential applications in advanced porous organic materials for fuel
