The H Type Electrochemical Cell has a great influence on the electrochemical measurement, especially in the polarization of the potentiostat. The electrolytic cell constitutes the feedback loop of the operational amplifier in the potentiostat. The change of the parameters of the electrolytic cell has a great influence on the stability of the potentiostat. influences. According to different test requirements, electrolytic cells include conventional electrochemical cells, H-type electrochemical cells, corrosion electrochemical cells, photoelectrocatalytic electrochemical cells, in-situ characterization electrochemical cells, and flow electrochemical cells,etc. The H Type Electrochemical Cell has a great influence on the electrochemical measurement, especially in the polarization of the potentiostat.
