Hydrogen energy membranes encompass materials, devices, and catalytic systems that couple water electrolysis and related electrochemical or photochemical reactions with selective ion and molecule transport. Work in this area develops membrane and electrode architectures for low‑platinum or platinum‑free hydrogen production, seawater and wastewater electrolysis, and integrated solar‑driven systems that simultaneously purify water and generate hydrogen. The field also includes gas‑separation and fuel‑cell membranes, membrane reactors for CO₂ conversion, and sensing and safety technologies that support hydrogen storage, distribution, and utilization.
