Researchers develop fuel cells for increased airplane efficiency


By Tina Hilding – Fuel cells offer a clean and highly efficient way to convert the chemical energy in fuels into electrical energy.

A solid-oxide fuel cell is similar to a battery in that it has an anode, cathode, and electrolyte and creates electricity. But it uses fuel to create a continuous flow of electricity. The process could be approximately four times more efficient than a combustion engine because it is based on an electrochemical reaction. The solid-oxide fuel cell is different from other fuels cells in that it is made of solid materials, and the electricity is created by oxygen ions traveling through the fuel cell. more> http://tinyurl.com/m6lrweo
