Performance Analysis of Pure Hydrogen and Mixed Fuels in Medium‐Temperature Metal‐Supported Solid Oxide Fuel Cell

open access: yesEnergy Technology, Volume 14, Issue 3, March 2026.
A novel mathematical model is developed for a multilayer metal‐supported solid oxide fuel cell (MS‐SOFC) designed for medium‐temperature operation at 600–700°C. The MS‐SOFC model is integrated with a steam reforming module to simulate the behavior of mixed fuels and evaluate their impact on fuel cell performance. A novel mathematical model is developed

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 86-105, March 2026.
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...
