Researchers in Germany (Forschungszentrum Jülich) developed two-phase ceramic membranes that significantly improve hydrogen separation throughput. These dense ceramic materials combine ionic and electronic conductivity, enabling hydrogen protons and electrons to move separately through the membrane — nearly doubling flow rates compared to earlier versions.

===== A team from the Chinese Academy of Sciences created a multilayer ceramic membrane via a novel “interface reaction-induced reassembly” technique. These membranes resist chemical degradation and maintain performance over 1,000+ hours of operation, which is a major step toward stability in real operating environments rather than short lab tests.

===== Proton-conducting ceramic membranes — essentially ceramic electrolytes that separate and transport hydrogen protons — have been integrated into reactors capable of producing hydrogen with ultra-low energy loss. In some research, this combines the chemical production and separation steps in one membrane system, potentially improving efficiency significantly at industrial scales.

===== Companies like NGK Insulators and MHI are actively combining ceramic membrane separation with ammonia/hydrogen cracking and purification — not exactly the same as production membranes but very relevant for hydrogen value-chain integration (e.g., cracking ammonia into hydrogen for transport and storage).
