Key Highlights
•
Researchers have developed a new strategy using copper-ion crosslinking to create thin, durable membranes for high-temperature fuel cells, overcoming a key limitation where thicker membranes were previously needed to prevent degradation. This breakthrough allows for significantly higher power density and longer device life, moving us closer to more efficient and practical hydrogen-powered vehicles.

Scientists found that using the fungus Penicillium citrinum to remove lead from geothermal brine is highly effective in freshwater, but its performance drops drastically in the salty, high-pressure conditions of actual geothermal power plants. This finding is crucial because it identifies high salinity as the main hurdle, guiding future research toward adapting biological methods for cleaning up geothermal energy systems.
