What are the key components of a fuel cell system?
Fuel cell stacks and system balance of plant (including reactant processors,
an invertor and the control system) are the key components. The fuel cell
stacks are typically the first item developed. The reactant processors
perform the integral function(s) of pre-conditioning the air and transforming
the fuel and water chemically and physically into a state where they can
be used by the stacks. These processors have been the developmental challenge
in most fuel cell system commercialization efforts. The control system
fine tunes the interaction between the processors and the stacks with
their related exhaust systems to correctly allow the working fuel system
to then produce electric power in its direct current state. The invertor
is the balance of plant piece that changes the direct current to alternating
current for commercial and household uses.
