How the fuel cell works
Each cell is made up of three distinct parts. The middle is a ceramic membrane. It's then sandwiched between an anode and a cathode. As gas is pumped in, the combination forces oxygen ions through the membrane. It's the movement of oxygen through the cell that creates the electricity.
What makes the system particularly special is that Bloom Energy has found a way to do this without having to use more expensive metals, and without it suffering degradation down to corrosion. The real question is whether this technology will be able to hold up past the company's 10-year warranty.
