How do hydrogen fuel cells produce electricity?

A fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the cathode, the protons, electrons, and oxygen combine to produce water molecules. Due to their high efficiency, fuel cells are very clean, with their only by-products being electricity, excess heat, and water.Click to see full answer. In respect to this, what is the science behind hydrogen fuel cells?A hydrogen fuel cell converts chemical energy stored by hydrogen fuel into electricity. A hydrogen fuel cell essentially consumes hydrogen and oxygen. When a fuel cell is continuously supplied with hydrogen and oxygen, and the product water is removed, the fuel cell can generate electricity.Likewise, where does the hydrogen come from for fuel cells? Hydrogen fuel can be produced from methane or by electrolysis of water. As of 2018, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming or partial oxidation of methane and coal gasification with only a small quantity by other routes such as biomass gasification or electrolysis of water. Also Know, what are hydrogen fuel cells and how do they work? But in general terms, hydrogen atoms enter a fuel cell at the anode where a chemical reaction strips them of their electrons. The hydrogen atoms are now “ionized,” and carry a positive electrical charge. The negatively charged electrons provide the current through wires to do work.What countries use hydrogen fuel cells? Countries like France, Norway, and Germany have made big strides to develop and deploy hydrogen fuel cells in a variety of applications. France. Norway. Germany.
