Investigadores de Hong Kong desarrollan acero inoxidable ultra resistente para hidrógeno verde

Un equipo de la Universidad de Hong Kong ha creado una nueva aleación de acero inoxidable que resiste la corrosión en la electrólisis de agua de mar. El material podría reemplazar los costosos componentes de titanio en los sistemas de producción de hidrógeno.

La aleación, conocida como SS-H2, fue desarrollada bajo el liderazgo del profesor Mingxin Huang en el Departamento de Ingeniería Mecánica. Emplea una estrategia de pasivación dual secuencial, formando una capa de óxido de cromo seguida de un escudo protector a base de manganeso que resiste potenciales de hasta 1700 mV. Este enfoque supera las limitaciones del acero inoxidable convencional, que falla alrededor de los 1000 mV durante la oxidación del agua en entornos ricos en cloruros.
