Electrochemical Technologies Laboratory

High-Temperature Zetameter

Used for measurements of electrophoretic mobility and zeta potential of particulate materials in high temperature solutions. The available instruments work at temperatures up to 250 °C and pressures up to 20 MPa. Samples with the particle size 0.1-1 micron can be studied.

Arbin Solid Oxide Fuel Cell Station

Can be used for testing single cells and stacks. The system includes Solartron electronics to perform sophisticated impedance analysis under open circuit or polarization conditions.

Scribner PEM Fuel Cell Station

Provides a capability for an automated control of gas flow rate, relative humidity, and temperature. The system includes Electrochemical fuel cell hardware and an acquisition system for data treatment and analysis.

Electrochemical Impedance Spectoscopy

Used for detailed electrochemical characterization of a variety of systems and processes, including fuel cell performance, corrosion, conductivity, and component degradation. Coupling EIS measurements with equivalent circuit modeling allows us to obtain specific impedance from various parts of the cell and restore the process mechanism.

Supercritical CO₂ Systems for Sequestration Research

Parr autoclave systems are used to study phase equilibria and metal corrosion in supercritical CO₂ fluid. The systems are equipped with both in-situ electrochemical probes and sampling vessels for ex-situ analysis.

Conductivity Measurements

Several electrochemical cells are available to test the ionic conductivity of membrane materials:

• Bekk Tech cell for in-plane measurements in gas phase with variable relative humidity
• Design made for testing inorganic conductors (pellets) in gas phase with variable relative humidity
• Clip cell for through-plane measurements in solution phase

CuCl Electrolyzer

To study the performance of various membrane materials and MEAs for hydrogen gas production from electrolysis of CuCl+HCl solutions. The system is designed to work with highly concentrated solutions up to 80 °C.
