The progressing climate changes lead to a revolution of power generation and energy conversion. The growing amount of renewable energy is a challenge for both power grid and storage. At the same time the reduction of carbon dioxid emission booms the market for electric mobility.

Both developments generate a huge demand on batteries and supercaps for energy storage. Besides, hydrogen as a suitable and portable energy storage raise the usage of fuel cells for electricity or hydrogen conversion.

Mobility applications require high reliable battery and fuel cell systems. This devices are replaced when a certain capacity or efficiency level is reached. The total lifetime of batteries and fuel cells introduce a new second life usage in less demanding markets.

Accessories

Electronic Loads

Electronic loads are indispensable tools in several fields of electrochemistry, for example in the research of batteries and fuel cells. Using an additional external power supply you easily can extend an EL to a two-quadrant potentiostat you need e.g. in the field of electrolysis.

External Power Potentiostats

Extend your electrochemical workstation, for example ZENNIUM X or ZENNIUM pro, with an external potentiostat to boost output current, enlarge compliance voltage or realize multi-cell arrangements.

PAD4 - 4-channel add-on card

The ZAHNER PAD4 is a 4-channel add-on card for ZENNIUM Electrochemical Workstations. It introduces four additional parallel sampled signal inputs for cell voltage and impedance in fuel cell stacks and battery packs, with a common current.

EPC42 - Controller Card for External Potentiostats 4 Channel

The EPC42 is a controller module for external potentiostats. Each EPC42 is able to address up to 4 PP/EL/XPot devices. Up to four EPC42 cards can be installed in a ZENNIUM X / ZENNIUM pro / ZENNIUM system. In total, an advanced ZENNIUM electrochemical workstation has the ability to control up to 16 external PPs/XPots.

PMux-P - Power Cell Multiplexer Segmented

The power cell multiplexer PMux can be used with ZENNIUM electrochemical workstations as well as with an external potentiostat from the EL-Series, PP-Series and XPot. It can manage a cell current up to ±5 A.

FRA Probe - Frequency Response Analyzer module

The FRA (frequency response analyzer) module interfaces third-party potentiostats and electronic loads to the ZENNIUM electrochemical workstations system. The external device must provide an analog control input and analog signal outputs for the measured current and voltage.

Noise Probe

The Noise Probe is a low power potentiostat for ZENNIUM electrochemical workstations specially designed for all common electrochemical noise techniques. In addition Zahner developed CorrElNoise®. This revolutionary new method is superior to common ECN techniques by avoiding most of their typical problems.
