【A fuel cell】

『Hydrogen ＋ oxygen＝electricity』

Do you know an experiment of an electrolysis 電気分解?When running an electric current into a water solution 水溶液 such as sodium hydroxide 水酸化ﾅﾄﾘｳﾑ,we can resolve water into hydrogen and oxygen.🙋

Contrary to it,reacting oxygen and hydrogen generates electricity.A fuel cell is a second electric battery which makes use of the reaction and generates electricity.💡

As for an ordinary second battery,whenever the electricity runs out,we have to charge and replenish the electricity,but as to the fuel cell,keeping on supplying hydrogen and oxygen which are fuel of the battery can continue generating the electricity.🙋
