摘要：
Novel fuel cell nanofibrous electrodes (NFEs) with a higher degree of platinum exploitation and higher durability compared to commercial standards are produced, based on self-standing electrospun carbon nanofibre webs covered by platinum ultrathin nanoislands deposited by high overpotential pulsed electrodeposition.
