New PEM Technology Reduces Hydrogen Storage Inefficiency by 60%

Korean researchers have engineered a SPAES polymer membrane that reduces toluene crossover by 60% in electrochemical hydrogen storage systems, significantly extending fuel cell lifespan. This breakthrough addresses a critical efficiency barrier in hydrogen fuel applications, arriving as Japanese researchers simultaneously demonstrate solid-oxide fuel cells operating at 572°F—less than half the conventional temperature requirement. The convergence of these advances suggests hydrogen storage technology is approaching critical efficiency thresholds for commercial viability.
