PGU-OEM H2 is a special version for permeation experiments in combination with our devanathancell. The device consits of two modules, one for the oxidation side and one for the charging side. Both modules are double galvanically isolated and can communicate with each other via EcmWin.
The idea of this design is the double galvanic isolation of the modules and the low noise setup by reducing cables and other parts which can catch disturbance from the environment. This is very important for hydrogen permeation measurement. Any leakage current between the devices on additional ways than via the electrochemical cell distorts the measurement result. By testing materials that are high resistant against hydrogen permeation for example, the expected permeation current is in a range of 5 to 10nA. Any leakage current could be higher if it is present.
