FTC320EX Hydrogen in oxygen analyzer | Oxygen analyzer in hydrogen
Hydrogen production by electrolysis of water refers to the dissociation of water molecules under the action of direct current to generate oxygen and hydrogen, which separate from the anode and cathode of the electrolytic cell. According to the different membrane materials of electrolyzer, it can be divided into three technical routes: alkaline electrolysis (AWE), proton exchange membrane (PEM) electrolysis and solid oxide (SOEC) electrolysis.
Proton exchange membrane (PEM) electrolysis of water for hydrogen production: PEM electrolysis of water for hydrogen production selects proton exchange membrane with good chemical stability, proton conductivity and gas separation as solid electrolyte, which can effectively prevent electron transfer and improve the safety of the electrolytic cell.
Principle of PEM electrolyzing water to produce hydrogen: the main components of PEM electrolyzer are proton exchange membrane, anode and cathode catalytic layer, anode and cathode gas diffusion layer, anode and cathode terminal plate, etc. Among them, the diffusion layer, catalytic layer and proton exchange membrane constitute the membrane electrode, which is the main site for the material transport and electrochemical reaction of the whole water electrolysis cell. The characteristics and structure of the membrane electrode directly affect the performance and life of the PEM water electrolysis cell.

Explosion proof glass bead filling option
Flammable and explosive gases may be introduced into the FTC320 In the analyzer. Here, the inner space of the shell is densely covered with glass beads (diameter 0.6mm ）。 In the case of explosive environment caused by unlikely leakage, the small space between glass beads prevents simultaneous ignition caused by analyzer failure.
Do not open the glass bead when it is loose FTC320 Housing. When the shell of the analyzer is opened, it may not work safely with flammable gas, causing explosion.
Anti condensation and dust handling options
When the desiccant or other drying equipment and particle filtration fail or have low efficiency, the measured gas may condense or large particles enter the analyzer, causing damage to the analyzer. The sensor inside the analyzer adopts one layer PTFE The coating protects the thermal conductivity sensor.
