1 Product Description

The ECC-Press test cell is dedicated to the measurement of the pressure build-up
during the electrochemical cycle. The low-dead-volume sampling port/valve serves to
draw gas samples from the cell’s headspace. The cell hardware is based on the
ECC-Std and ECC-Ref test cells and can be used with or without a reference
electrode.

The ECC-Press comes with a controller box for easy interfacing with an external
potentiostat. Analog outputs for both pressure and temperature are provided for
seamless integration with external instruments. As an option, all relevant signals of
the experiment – cell pressure, temperature, cell potentials and current – may be
recorded with an integrated USB data logger (DL option).

This manual covers only the special features of the ECC-Press and ECC-Press-DL. It
is assumed that the reader is already familiar with the assembly and operation of
both the ECC-Ref and the ECC-Std test cell.

2 Features and Specification

 Precise pressure sensor attached to the electrochemical cell for monitoring

pressure changes during charge / discharge

 Sampling valve with septum port for drawing gas samples by means of a

syringe

 Default pressure range of 0 to 2.5 bar (absolute)
 Leakage tested; after 24h the pressure changes by less than 0.2 mbar/h

(tested with PEEK lid seal, air, 2 bar, 50°C, both spacers installed)

 Conditioning electronics with analog outputs for pressure and temperature
 Optional integrated USB data logger for recording of cell pressure,

temperature, cell potentials and current

 Adjustable dead volume between 3.024 cm3 and 6.172 cm3.
