Understanding the difference between battery and fuel cell is important, especially for those who want to select the most appropriate energy solutions, both for electric vehicles, electronic devices, and energy generating systems. The major difference between batteries and the galvanic cells is that commercial typically batteries use solids or pastes rather than solutions as reactants to maximize the electrical output per unit mass. See how different types of fuel cells compare with one another. The mechanics are similar to batteries, with each cell containing a positive electrode (cathode) and negative electrode (anode) separated by an electrolyte. A fuel cell is a special type of battery in which the reactants are supplied from an external source as power is produced. Air is directed to the cathode while a feedstock like hydrogen is fed to the anode. It provides details on how batteries work including definitions of anode, cathode and amp-hours. The hydrogen fuel cell uses hydrogen and oxygen from the air to produce water, and is generally more efficient than internal combustion engines.
