| Although superficially similar to a battery, a fuel cell gets its energy in a different way. |
| Pressure and gravity refueling receptacles are installed in the aft port fuel cell. |
| For less than the cost of developing a fuel cell you can modify a current engine to run on hydrogen. |
| The micro fuel cell is a standalone device shaped like a cradle for recharging handsets. |
| The amount of electricity the fuel cell produces depends on the size of the cell as well as the rate of flow of the hydrogen. |
| That's the promise of the miniaturized fuel cell, which could end the long run of the storage battery. |
