  text: If proton exchange membrane fuel cells (PEMFC) are ever to succeed in sustainable
    energy landscape as a potential zero emission technology, it is inevitable to
    reduce electricity production cost associated mainly with its MEAs, cell hardware
    and gas storage units. We demonstrate a diverse strategy for achieving this target
    with a concomitant amplification of its specific energy and power, by rolling
    a thin graphene oxide (GO) based MEA alone into a tubular and air breathing architecture
    with internal fuel storage. The unique properties of GO being a barrier for molecular
    fuels and proton conducting to construct a GO based cylindrical MEA. This makes
    the tubular PEMFC ∼75 times lighter, featuring ∼37 and ∼92 times respectively,
    the power and energy per overall weight, making it a potential candidate for portable
    applications. The intrinsic electrochemical kinetics at the three-phase boundary
    are somewhat affected by the bending of the MEA, albeit at overall reduction in
    power production cost.
