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.","lang":"eng"}],"extern":"1","quality_controlled":"1","author":[{"last_name":"Thimmappa","first_name":"Ravikumar","full_name":"Thimmappa, Ravikumar"},{"first_name":"Mruthyunjayachari","last_name":"Chattanahalli Devendrachari","full_name":"Chattanahalli Devendrachari, Mruthyunjayachari"},{"last_name":"Shafi","first_name":"Shahid","full_name":"Shafi, Shahid"},{"last_name":"Freunberger","orcid":"0000-0003-2902-5319","first_name":"Stefan Alexander","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander"},{"last_name":"Ottakam Thotiyl","first_name":"Musthafa","full_name":"Ottakam Thotiyl, Musthafa"}],"date_published":"2016-12-21T00:00:00Z","article_processing_charge":"No","date_updated":"2021-01-12T08:12:49Z","doi":"10.1016/j.ijhydene.2016.08.057"}]
