Science Vision, 15(2), 41-47.https://repoemc.ukm.my/handle/123456789/655Fuel-cell technology, using hydrogen energy, is an advanced green energy technology for the future that is green, sustainable, clean and environment- friendly. Emission of Green-house gases from human activities has been proven beyond doubt as the main cause of global warming and climate-change. The finite world energy-supply, which consists nearly of 90% fossil fuel, will be depleted in a short period of time precipitating an energy-crisis because of a widening gap between fossil-fuel production and demand. Many countries responded to the anticipated energy crisis by diversifying their fuel-resources to include renewable and alternative energy, and developing green-energy technology for the future. Despite political announcements on renewable energy, fossil-fuels will continue to dominate energy resources for some time in future, and carbon emission will increase; but global nuclear energy expansion is uncertain because of international tensions and general public fears of another Chernobyl disaster or a nuclear terrorists.Hydrogen economygreen energyfuel cellnanomaterialsnanostructuressolar hydrogen.Journal
