Electrode Specifications
Source-supported electrode parameters
11 specifications, each mapped to a discrete fact from our published test data: HER and OER overpotentials, the electroless deposition process, the Ni foam substrate, the 5 cm² AEM test cell, and the dynamic-load and 1000-hour stability runs.
Key parameters at a glance
All values as-measured, without IR correction where applicable.

HER OVERPOTENTIAL
HER Overpotential 80 mV at 100 mA/cm2
Measured on our bifunctional NiCo electrode in 30 wt% KOH at 100 mA/cm2 without any IR correction. The same coated electrode also ...
OER OVERPOTENTIAL
OER Overpotential 260 mV at 100 mA/cm2
Measured on our bifunctional NiCo electrode in 30 wt% KOH at 100 mA/cm2 without any IR correction. The same coated electrode opera...
OPERATING POINT
Industrial Current Density at 0.5 A/cm2
Our published 1.62 V cell voltage at 0.5 A/cm2 (60 deg C, AEM cell with bifunctional NiCo and commercial Zirfon separator) corresp...
BIFUNCTIONAL
Bifunctional HER/OER Architecture
The same coated NiCo electrode operates as both HER cathode and OER anode. Measured at 100 mA/cm2 in 30 wt% KOH without any IR cor...
CATALYST
Nickel-Cobalt Bi-metallic Catalyst
Our active layer is a bi-metallic catalyst combining nickel and cobalt. Both are first-row transition metals. The catalyst is elec...
SUBSTRATE
Nickel Foam Substrate (100 to 1000 cm2)
Our electrode is built on Ni foam: an open-porosity nickel substrate that supports three-dimensional catalyst coverage. Substrate ...
DEPOSITION
Electroless Deposition Process
Our bifunctional NiCo catalyst is deposited on Ni foam by an electroless process. Electroless deposition does not require an exter...
STABILITY
1000-Hour Stability at 21 uV/hr Drift
A continuous 1000-hour chronopotentiometry on our bifunctional NiCo electrode in an AEM cell at 0.5 A/cm2 and 40 deg C in 30 wt% K...
SOLAR CYCLING
Solar Dynamic Load (9-day Continuous)
Solar-irradiance data sampled sunrise to sunset was converted into a current-density schedule and applied to our bifunctional NiCo...
WIND CYCLING
Wind Dynamic Load (100-hour Continuous)
Wind-speed variation data over 100 hours converted to a current-density schedule (0 to 0.78 A/cm2) and applied to our bifunctional...
