Fuel cell

Fuel cell,

Definition of Fuel cell:

  1. Device that converts chemical energy of a fuel (usually hydrogen) directly into electrical energy. In this process hydrogen is continuously passed over a porous nickel or platinum alloy cathode that splits the hydrogen into electrons and protons. The electrons pass through an external circuit whereas the protons (after passing through a liquid or membrane electrolyte) travel to a porous carbon anode over which oxygen is continuously passed to yield water. The efficiency of fuel cells (80 percent) is well over twice that of other such devices, but they are bulky and require constant supply of gases. Their main use is in spacecraft and submarines, and the possibility of using them in cars is being explored. Invented in 1854 by the UK physicist William Robert Grove (1811-1896).

  2. A cell producing an electric current directly from a chemical reaction.

How to use Fuel cell in a sentence?

  1. A good fuel cell can help you to get the most out of your energy and keep the costs down to a minimal level.
  2. To fix it, the mechanic had to replace a fuel cell , which would cost me a little more than I hoped.
  3. When you are working in an industrial plant having a quality fuel cell can help to keep your overall costs down.
  4. The micro fuel cell generates electric power through a chemical reaction by mixing hydrogen and methanol.

Meaning of Fuel cell & Fuel cell Definition

Fuel Cell

Inexpensive miniature power technology. Like batteries, fuel cells generate electricity through a chemical reaction. However, fuel cells are charged by adding or replacing chemicals (such as hydrogen, methanol, or aluminum mixed with oxygen in the air) rather than plugging the charger into a wall outlet. Fuel cells have a much higher energy density than lithium and can power demanding devices for longer. Choosing a stable, safe and readily available fuel source and miniaturizing small equipment while maintaining efficiency remain challenges.
