text: Furthermore, a fuel cell is continuously supplied with fuel and oxygen from an external source, which makes it work for a long time period; however, a battery contains a limited amount of fuel and oxidant, and these two components decrease with time, so this device cannot supply electrical energy for a long period of time.
text: A fuel cell must continuously be supplied with fuel and oxidant to produce electricity.
text: Fuel cells are like batteries in that they are electrochemical devices, but unlike batteries do not need recharging and will continue to operate as long as they are provided with fuel (hydrogen).
