A new study aims to optimize the flow channel design of PEMFCs to enhance their performance. In their article published in Frontiers in Energy, Youliang Cheng and colleagues propose a 2D topology ...

Topological insulators are materials that are insulating in their interior but can support the flow of electrons on their surface. The underlying cause is time-reversal symmetry: their physics is ...

A 650-V bi-directional GaN IC combined with a high-speed isolated gate driver facilitates this single-stage power conversion.
