Why does fuel cell not burn?
From the appearance of positive and negative electrodes and electrolytes, like a battery, but in essence it can not "storage" but a "power plant." However, it requires electrodes and electrolytes as well as redox reactions to generate electricity.
The principle is not the same ~ hydrogen fuel cell is the device will separate the hydrogen and oxygen and then combined with the discharge process and the ignition is a direct chemical reaction ~
For a fuel cell, a fuel cell is a power generation device that converts chemical energy present directly in the fuel and oxidant into electrical energy. Fuel and air were sent to the fuel cell, electricity was wonderful to produce it.
