A-2：All-solid-state battery

---

Chemical and electrochemical instabilities at the interface and an increase in ionic conduction resistance are major problems in all solid state cells with sulfide electrolyte systems. The oxide electrolyte system has a higher electrochemical stability than the sulfide system, but has ...

B-2：Electrolyte membrane and proton transport in fuel cell

---

The electrolyte membrane bulk and the four-phase interface itself are responsible for the transport of active materials such as protons, oxygen, and hydrogen, and control them as functions at the molecular level. Therefore, further enhancement of performance ...
