O Continued to conduct
research to provide
technology needed to
increase life and
reliability of this
high-energy battery by
investigating improved
corrosion-resistant
case material, devel-
oping stronger elec-
trolytes, and evaluated
new cell designs to
improve freeze-thaw
resistance. Also
analyzed cell inter-
connection strategies
and thermal control
techniques to maximize
battery survival of
cell failures. ($4,447)
Continued investigat-
ing long-term stabil-
ity of polymeric
materials and active
materials for the
potentially low-cost,
high-energy zinc/
bromine battery.

Continued to conduct
experiments on stand-
alone electrolyzer
systems including the
static feed water sys-
tem which is capable of
electrolyzing sea water
directly. Conduct re-
search on intermediate-
(300-500°C) and high-
temperature (1000°C)
electrolysis for the
production of hydrogen.

Conduct long-range R&D o
addressing the use of
hydrogen as a cost-
effective energy
carrier and storage
medium for energy
produced from solar
and other inexhaust-
able resources. R&D
will include studies
of hydrogen production
options such as high-
temperature electroly-
sis of water vapor and
dissociation of mole-
cules by direct
irradiation with
concentrated sunlight.
Investigate storage
options such as
refrigeration by adia-
batic demagnetization,
metal-assisted cold
storage, and advanced
metal hydride research
to achieve lower cost
in liquefying hydrogen
for storage. ($995)

Continue long-range R&D
on the use of hydrogen as
a cost-effective energy
carrier and storage
medium for energy pro-
duced from solar and
other inexhaustable
resources. Research will
include: multicell

modules in high

temperature electrolysis
of water vapor; proton-
conducting solid elec-
trolytes in medium-
temperature electrolysis
and dissociation of water
using polymeric-coated
photoactive semiconduc-
tors. Investigate metal
assisted cold storage and
advanced metal hydrides
to achieve lower cost in
liquefying hydrogen for
storage. ($1,000)
