    Fuel cell breakthrough

    Scientists at the Harvard School of Engineering and Applied Sciences and SiEnergy Systems LLC have demonstrated the first macro-scale thin-film solid-oxide fuel cell. This is the first time a research group has overcome the structural challenges of scaling up the technology to a practical size with a proportionally higher power output.
