Predicting the system efficiency of green energy and developing forward-looking power technologies are key points to accelerating the global energy transition. This research focuses on optimizing the parameters of proton exchange membrane fuel cells (PEMFCs) and photovoltaic (PV) cells using the honey badger algorithm (HBA), a swarm intelligence algorithm, to accurately present the performance characteristics and efficiency of the systems. Although the HBA has a fast search speed, it was found that the algorithm's search stability is relatively low. Therefore, this study also enhances the HBA's global search capability through the rapid iterative characteristics of spiral search. This method will effectively expand the algorithm's functional search range in a multidimensional and complex solution space. Additionally, the introduction of a sigmoid function will smoothen the algorithm's exploration and exploitation mechanisms. To test the robustness of the proposed methodology, an extensive test was conducted using the CEC'17 benchmark functions set and real-life applications of PEMFC and PV cells. The results of the aforementioned test proved that with regard to the optimization of PEMFC and PV cell parameters, the improved HBA is significantly advantageous to the original in terms of both solving capability and speed. The results of this research study not only make definite progress in the field of bio-inspired computing but, more importantly, provide a rapid and accurate method for predicting the maximum power point for fuel cells and photovoltaic cells, offering a more efficient and intelligent solution for green energy.

Bifunctional oxygen electrocatalysis is a pivotal process that underpins a diverse array of sustainable energy technologies, including electrolyzers and fuel cells. Metal selenides have been identified as highly promising candidates for oxygen electrocatalysts with electronic structure engineering that lies at the heart of catalyst design. Two-phase Fe-doped nitrogen carbon (NC)-supported nickel selenides were synthesized using a coordination polymer template.

Permeance-selectivity trade-offs are inherent to polymeric membranes. In fuel cells, thinner proton exchange membranes (PEMs) could enable higher proton conductance and increased power density with lower area-specific resistance (ASR), smaller ohmic losses, and lower ionomer cost. However, reducing thickness is accompanied by an increase in undesired species crossover harming performance and long-term efficiency.

Electrochemical devices that can operate at temperatures of 200-300 °C are expected to become the next-generation energy conversion devices in fuel cells and electrosynthesis, which are important for achieving carbon neutrality. Proton conductors based on phosphate glasses are being developed as candidate materials for such devices. We recently developed a glass proton conductor by using silicophosphoric acid based on the idea of solidifying phosphoric acid with silicon as a cross-linking glass framework.

Enhancing the catalytic performance and durability of M-N─C catalyst is crucial for the efficient operation of proton exchange membrane fuel cells (PEMFCs) and Zn-Air batteries (ZABs). Herein, an approach is developed for the in situ fabrication of a MOFs-derived porous carbon material, co-loaded with Co nanoparticles (NPs) and Co-N sites and integrated onto Fe-doped carbon nanotubes (CNTs), named Co-NC/Fe-NCNTs. Incorporating polymer-wrapped CNTs improves MOFs dispersion annealing at high temperature, which amplifies the three-phase boundary (TPB) by generating much more mesopores and exposing additional active sites within the catalysts layer.

Background: Amplified imaging of microRNA (miRNA) in cancer cells is essential for understanding of the underlying pathological process. Synthetic catalytic DNA circuits represent pivotal tools for miRNA imaging. However, most existing catalytic DNA circuits can not achieve the reactant recycling operation in cells and in vivo.
