This study focuses on developing fuel cell power technology for charging superconducting coils using variable resistor. For this purpose, a variable resistor is fabricated, and experimental equipment is built to control the amount of current applied to the superconducting coil by fixing the amount of gas supplied to the fuel cell and adjusting its driving voltage. The current and magnetic flux densities increase and decrease depending on the variable resistor. A variable resistor is modified by considering the characteristic curve of the fuel cell, and the flow rate supplied to the unit cell is controlled to overcome inefficient energy use. The amount of current charged to the superconducting coil increases depending on the supplied flow rate. Therefore, the measured magnetic flux density increases according to the charged current. Consequently, the fuel cell characteristic evaluation results and data measured while driving the superconducting coil are almost identical.

To enhance the electrocatalytic performance of a flexible Pd@CFs catalyst for methanol oxidation, deep cryogenic treatment in liquid nitrogen was introduced. The effects of the frequency and time of the deep cryogenic treatment on the surface crystal orientation, microstructure morphology, mechanical performance, and electrocatalytic performance for methanol oxidation were studied. The results showed that when the frequency of the deep cryogenic treatment was 2 times and the deep cryogenic time was 24 h, the electrocatalytic performance of the catalyst was the best.

Platinum-based nanoalloys are efficient electrocatalysts for the oxygen reduction reaction (ORR). measurements have revealed that key properties including induced strain, chemical composition, coordination environment, evolve significantly during operation, which can hampertheir effective implementation in fuel cells. In fact, recent studies indicate that the impact of the early surface activation steps of Pt-based nanoalloys has been hitherto underestimated and is an important factor contributing to loss of their initial electroactivity.

Microbial Electrochemical Technology (MET) offers a promising avenue for CO utilization by leveraging the ability of chemolithotrophic microorganisms to use inorganic carbon in biosynthetic processes. By harnessing the power of electroactive bacteria, METs can facilitate the conversion of inorganic carbon into organic compounds. Therefore, this work combines biosurfactant production at the anode and PHB production at the cathode of Microbial Fuel Cells (MFCs), while testing the efficiency of Microbial Electrosynthesis Cells (MECs), and traditional culture in liquid media.
