Scientists have unlocked a surprising clean energy breakthrough using an unlikely source from the poultry industry. In a potential breakthrough for green energy technology, scientists at ETH Zurich and Nanyang Technological University Singapore (NTU) have developed a membrane for hydrogen fuel cells made from discarded chicken feathers—an abundant waste product in the global poultry industry. The new membranes are made from keratin, a structural protein that makes up the bulk of feathers. Extracted and processed into amyloid fibrils, the keratin forms a thin, proton-conductive layer at the heart of a hydrogen fuel cell. According to the research team, the material...
