Fuel Cell: Working Principle, Characteristics, Systems, Advantages
The fuel cell stack consists of a group of fuel cells that are connected and bound together to provide increased electrical power. The output voltage of a single fuel cell is very small (about 0.7 V), so fuel cells are connected (stacked) in series to increase the voltage and in parallel to increase the amount of current they can provide.
