What Is Fuel Cell?

Fuel cells are the future and the present. They're everywhere, and you probably have yet to notice. That's because they're so small and ubiquitous that they blend into the background of your life, like all of those little things that make your day just a little bit better. You don't even notice them until you miss them when they're gone—and then you realize how much better everything would be if only those little things were still there. In the world of electricity, fuel cells are like the old-fashioned flip phones of the early 2000s. They're still around and helpful, but they're less cool than the modern smartphones you're used to. Fuel cells produce electricity using chemical energy generated through a chemical reaction between positively charged ions and an oxidizing agent. They consist of an electrolyte and two electrodes—An electrode with a positive charge is named the anode, and an electrode with a negative charge is named the cathode. Electricity can be generated by combining hydrogen and oxygen in the right proportions. Despite its simplicity, this method proves to be more efficient than any other. The system involves two electrodes in a cell containing either water or carbon dioxide As these chemicals react, fuel is consumed, and an electric current is created. Whenever chemicals flow into the cell, they trigger the flow of electricity between the electrodes, which then provides electricity outside the cell. This electric current is known as the load. Unlike conventional batteries, which must be recharged after a while, the cell never dies as long as chemicals continue flowing into it. You know what we're talking about: that morning cup of coffee that gets you going or the warm hug from a loved one when you need it most. Fuel cells are like that, but better—instead of just giving us warmth and comfort and caffeine, fuel cells provide us with electricity!
