unique missions that require low thermal
signature, low noise level, and increased
endurance relative to batteries.
To enable fuel-cell stack operation and
control, a balance-of-plant (BOP) containing
additional systems is required. The BOP,
which accounts for the majority of total fuelcell system weight and volume, includes fuel
and air supply systems, a water-management
system, and a thermal-management system.
For power conditioning and control to meet
the load demand, the fuel cell BOP also
requires a power-management system.
High power density design
Water is critical to the performance and
durability of a PEFC. The transport of protons
through the polymer membrane depends on
water as each proton (H+) migrates through
the micro-pores of the membrane in the form
of H3O+ dragging molecules of water from the

anode to the cathode, a phenomenon known
as electro-osmotic drag.
Inadequate membrane hydration can lead
to cell performance loss due to high
resistance to proton transport through the
membrane. In addition, drying of the PEFC
induces mechanical stress and chemical
degradation of the membrane, which can
result in performance failure.
Traditionally, the membrane is hydrated
through humidified reactant gases. The
saturation level of these gases as well as the
operating conditions of a PEFC require an
intricate water-management system to
maintain good and stable performance
under steady-state as well as transient
conditions. This requires maintaining a
balance of all the forces that impact water
transport in the cell (e.g., electro-osmotic
drag, water production, and water vapor
entering and exiting the fuel cell).
Insufficient water can lead to membrane
dry-out and hence performance degradation.
Too much water can block reactant flow
fields, which can result in severe performance
losses. In addition, the presence of excessive
liquid water can restrict reactant gas transport
to the electrodes and can result in severe
performance losses.
Traditional PEM fuel cell systems often
employ specific cell designs and operational
methods that provide high reactant pressure
drops in the cathode and anode with the
need for accurate temperature and humidity
control to help in alleviating excess water in
the stack and reduce the impact of
“flooding.”
Such strategies generally render the fuel
cell system more complex, more expensive,
and less efficient. UTC’s PEM stack
technology effectively overcomes watermanagement issues in a simple and passive
