9.3.4.2 Design of Cell Stack
9.3.4.2.1 Power Output and Energy Efciency
There are two important technical parameters that need to be considered in
the design of the cell stack: power output and EE, which can be expressed as
P
out
= I
app
× A × V
ave
× N (9.1)
EE = CE × VE (9.2)
where P
out
is the power output, I
app
and P
ave
represent the applied current
density and average voltage of single cell, respectively, and A and N are the
