Based on our experience in small fuel cell
power sources integration systems, we are developing a basic line of PEM
fuelcell power units in the range 25 ..100 W.
They are based on 100 sq.cm. active area cells in order to reduce as much
as possible the number of cells in the stack. The main reason of this is
improvment of the power controll of each cell and significantly increasing
MTBF of the entire stack.
Covering the range 25...100 W continuous power with this technique is
possible with stacks containing 1 to 5 cells only.
An embedded controll system based on single RISK controller drives the
system, ballansing according to humidification the Air stochiometry
conditioning and High efficiency DC-DC converting with stable voltage
output in the range 14 up to 56 V.
25 W 14 V output power source
50 W 14...28 V output power source
100 W 14...56 V output power source
