Large stack EL
The FRA-X acts as an interface between the IM7 series potentiostat and an external power supply, enabling EIS measurements outside the power specifications of Zahner's products. Such a system can be used to carry out reliable EIS on large electrolyzer stacks. The FRA-X supports voltages up to 1400 V and currents up to 2000 A.
Synchronous per-cell measurement separates the ohmic, charge-transfer, and mass-transport contributions to the overpotential and identifies the cells that limit overall stack efficiency, which a single voltage measurement cannot provide.
The optional PAD42 cards enable synchronous measurements on individual cells within a stack, half-cell characterization, and cross-sectional analysis, allowing more detailed evaluation of electrolyzer stacks.
The system can be controlled through Zahner Lab software or integrated into automated setups via C++, Python, or WebSockets.
Technical specifications
In-depth electrolyzer analysis
The PAD42 cards in the IM7 or IM7x can be used together with FRA-X to perform synchronous measurements for in-depth analysis of the electrolyzer stacks.
Stack-level analysis
The PAD42 cards allow synchronous EIS or DC measurements on each cell in a stack. With eight PAD42 cards, up to 33 synchronous measurements can be carried out on individual cells in a stack.

Half-cell analysis
The PAD42 cards in the IM7 or IM7x can be used to perform synchronous measurements at each electrode in a reference electrode setup.

Electrode-level analysis
The PAD42 cards (with segmented shunts) enables cross-sectional analysis of the cell.
