Bin Zhu is a Swedish citizen, 1989 as a researcher invited to Chalmers University of Technology, Sweden for fuel cells, and got PhD in 1995. During 10/ 95-12/97 worked as Postdoc. in Uppsala University (Ångström Lab). Since 1998, Dr. Zhu moved to KTH and in 1999 became associate professor (docent) in KTH with 20 years. He had been visiting professor in Aalto University and Nanyang Technological University and professor in several Chinese universities, and currently in Loughborough University, UK. https://www.lboro.ac.uk/departments/aae/staff/bin-zhu/. Prof. Zhu has been selected by Chinese overseas talent programs in Hubei province and also in Jiangsu province. 2020-2025 five and half year as an oversea Changjiang professor in Southeast University. Zhu is one of the Most Cited scholars in China (Energy sector, Elsevier).Professor Zhu Bin has published over 450 papers (cited over 19,800 times on Google Scholar, with an H-index of 72) in the fields of nanocomposites and novel semiconductor-ionic materials (SIMs) for superproton conductors and advanced fuel cells/solar cells, covering materials, devices, and technologies.

Semiconductor Ionics represents a transformative frontier that bridges solid-state physics, electrochemistry, and materials science. By coupling electronic and ionic transport within semiconducting matrices, it enables a new class of materials and devices that surpass the limitations of classical ionics. Building upon this framework, Topological Protonics further extends the concept to quantum and spatially coherent proton transport, where the interplay of symmetry, electronic structure, and built-in electric fields governs proton motion and energy conversion efficiency.This lecture will introduce the evolution of semiconductor ionics—from traditional YSZ and doped ceria systems to semiconductor-ionic composites and heterostructures—and discuss how electron–ion coupling, proton–electron spillover, and photo-semiconductor electrochemistry with application in low-temperature 300–500 °C ceramic fuel cells as the example. By integrating theoretical insights, defect chemistry, and DRT–EIS analyses, we will explore how semiconductor ionic and topological design principles can lead to superionic behavior and multifunctional devices that unify fuel cells, proton battery, electrolysis, and photoelectrocatalysis. The talk aims to provide young researchers with a conceptual and practical roadmap toward next-generation sustainable energy technologies driven by Semiconductor Ionics and Topological Protonics.
