 ACT\n\nDeveloping efficient electrode catalysts for water electrolysis and
  fuel cells is essential to building a sustainable hydrogen society. These
  catalysts enable the conversion of water into hydrogen and oxygen\, provi
 ding a renewable hydrogen source for clean energy. Additionally\, stable e
 nergy storage is necessary to balance the intermittent nature of renewable
 s like solar and wind. High-capacity\, long-life batteries play a critical
  role in maintaining this energy supply consistency\, bridging the gap whe
 n renewable sources fluctuate. Electrochemistry is central to these advanc
 ements\, providing crucial insights into reactions at the metal-electrolyt
 e interface. These insights are essential for improving energy conversion 
 efficiency\, energy storage\, and corrosion reduction.\n\nOver the past tw
 o decades\, our research group has dedicated itself to developing theoreti
 cal models and simulation techniques to understand these complex electroch
 emical reactions.[1] These models help reveal the detailed interface mecha
 nisms\, advancing fundamental knowledge. In this talk\, I will introduce r
 ecent applications of our simulations. First\, I will discuss our work on 
 a newly developed oxygen evolution electrode (r-BS)\, focusing on its acti
 ve sites for water electrolysis. Further\, I will also present our recent 
 studies on surface stress at electrode surfaces under applied bias voltage
 s [3] and on corrosion mechanisms at metal/oxide interfaces [4].\n\n[1] M.
