Fuel Cells Are Not Necessarily Hydrogen-Based[edit]

Solid oxide and molten carbonate fuel cells operate using negative ion transport, so the initial definition of fuel cell is incorrect, being too narrow: "A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent." In fact, a fuel cell in general is a device for converting chemical energy in fuel to electricity by ion transport across an electrolytic barrier, with hydrogen ions being easiest to transport and therefore hydrogen-ion fuel cells being the most common and most successful to date. Furthermore, negative-ion-transport fuel cells do not necessarily have an "internal reforming" process, and the primary chemical equations for them are those of carbon oxidization. For example, if coal were being used directly in a molten carbonate fuel cell, hydrogen would not even be present. — Preceding unsigned comment added by 198.208.159.19 (talk) 19:31, 3 May 2017 (UTC)
