Meeting your needs at DoppStein
Laboratory
DSE
Capabilities
- Develop
hydrogen and oxygen generation cells from laboratory-made electrodes.
- Develop
gas electrodes specific for your needs. Current nano Nickel/Cobalt
catalysts are proving to be nearly as active as Platinum for oxygen
reduction at a fraction of the cost.
- Develop
battery and fuel cells from custom-made cathodes.
- Electrochemical
testing and evaluation of gas electrodes produced elsewhere for
functionality and failure analysis. Testing would include electrochemical
and impedance spectrographic analysis. Evaluation and recommendations
would follow thorough testing.
- Creative
approaches to client needs.
- Skilled at cell manufacturing line
design & troubleshooting.
- Cell optimization studies and Cell
failure analysis including internal and reference electrode work.
- Creative electronic circuit designer
and builder. Have created
many test and application circuits.
- Government contract experience
(e.g.: CECOM, SBIR grants)
- Work closely with patent attorneys
and Patent Office.
Substantial patent portfolio.
- Mentor of young scientists and
engineers to learn how to expand their horizons of thought.
Water
Electrolysis Equipment:
Many
test reactors have been made both in the half-cell and whole cell design to
optimize hydrogen (and oxygen) production in alkaline electrolytes. Flat plate designs are running at high
efficiencies in creative assemblies for robust performance in many
applications. Devices using a pent
pending Fluidized Bed design are running typically at energy efficiencies above
90% at 5 Amps/cm2.
Gas
Electrode Expertise:
Laboratory
Cathode Machine capable of producing gas diffusion
cathodes from as little as 5 grams of active mix up to nearly continuous
production. Current experiments are optimizing the use of nano sized particles
of nickel, cobalt, silver, their alloys and oxides to catalyze the reduction of
oxygen with alkaline electrolytes. The results
are cathodes which are as thin as .002" (.05 mm) and with ambient limiting
currents well above 750 mA/cm^2, and power over 400 mW/cm^2. The mid-Tafel CCV
is approaching that of a fully platinized cathode. Applications are metal air
batteries, fuel cells and hydrogen generation applications. Testing of these electrodes include a
wide array of electrochemical and impedance studies.
