Single cell FC
Electrochemical impedance spectroscopy (EIS) is a key technique for fuel cell research, for example on PEM and solid oxide fuel cells. It separates the individual loss mechanisms inside a cell, such as ohmic membrane resistance, charge transfer resistance, and mass-transport limitations.
Measured alongside the polarization curve, these contributions show where a single cell loses efficiency under real operating conditions. This makes EIS well-suited to studying membrane hydration, flooding and drying, and catalyst degradation.
The EIS-capable PP2x2 series power potentiostat provides a flexible 200 W solution for fuel cell characterization. Systems are available with current ranges of ±10 A, ±20 A, or ±40 A.
The optional PAD42 card extension enables synchronous half-cell characterization and cross-sectional analysis of the cell, allowing for more detailed evaluation of the fuel cell.
The system can be controlled through Zahner Lab software or integrated into automated setups via C++, Python, or WebSockets.
The PP2x2 series power potentiostat is used as an extension of an IM7 or IM7x potentiostat.
