A Deeper Dive into Hydrogen Fuel Cells
History and Development of Hydrogen Fuel Cells
Hydrogen fuel cells were first conceptualized in the early 19th century. Over the decades, advancements in technology and materials have transformed them from laboratory curiosities to viable energy solutions.
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. https://en.wikipedia.org/wiki/Fuel_cell
