The Major Advantage of a Fuel Cell Over a Standard

The major advantage of a fuel cell over a standard battery is that

A) fuel cells are less expensive to produce and operate than standard batteries.
B) a fuel cell generates electricity without the need for positive or negative electrodes but batteries have these electrodes.
C) fuel cells produce power as long as they are supplied with fuel whereas batteries store a fixed amount of energy.
D) fuel cells generate small amounts of CO₂ and sulfur oxide emissions compared to the large amounts emitted by standard batteries.
E) fuel cells do not have any advantages over standard batteries
