Fuel Cell Poisoning Module

This module is designed to test PEM fuel cell catalyst poisoning and enables reproducible and accurate investigations from 1 ppm concentration of poisoning gas.


It permits to simultaneously dose a precise amount of different poisoning gases into the fuel cell stack anode or cathode working gas flow. Additionally, one poisoning liquid substance can be mixed to the fuel cell working gas as option. The system is dedicated to cover large range of poisoning gas concentrations from 1 ppm (10-6) to 10 ppt (10-2) at a minimum working gas mass flow of 100 mln/min.

The module can be connected and controlled by the LEANCAT test bench automation system or your own existing test bench (via OPC UA server). The system of the mixer makes use of advanced mixing technology developed by Leancat. The technology is capable of achieving 1ppm concentration in the whole flow ranges > 100 mln/min.
