Products powered by fuel cells, such as robots and small submarines, have already been developed in various advanced countries around the world. In Japan, fuel-cell-powered electric cars have been successfully developed; manufacturers expect to build 50,000 units in 2010, and 5 million by 2020. By that time, filling stations will offer hydrogen in addition to traditional fuels.
目前世界各先進國家都已經研發出燃料電池的各項相關產品，像機器人、小型潛水艇等，日本也已成功發展出多款使用燃料電池的電動車，預計二○一○年時可量產五萬輛，並於二○二○年達到五百萬輛的經濟規模，屆時的傳統加油站旁，就會有氫氣加油站的設置。
