Hydrogen is the simplest most abundant element in nature. It exists as a hydrogen molecule H2 gas under standard conditions. A fuel cell is a device that uses hydrogen as a fuel to generate electricity. There are many ways to generate hydrogen gas. The most used method currently is to use natural gas CH4(Methane) to generate hydrogen molecules. Electrolysis of water is also popular but it uses a lot of electricity. Using sewage to generate hydrogen is also being used similar to the natural gas process. There are other ways as well but these are the most widespread currently. Hydrogen as a resource is basically inexhaustible. The challenge is to generate it while producing few harmful emissions i.e. using renewable energy.
