OPERATION - ELECTROLYSIS

Membrane consists of a proton-conductive solid polymer electrolyte and porous electrodes with a catalytic layer composed of noble metal.

A D.C. voltage is applied to the porous electrode attached to the membrane. This results in splitting the water on the anode side (dehumidifying side) into Protons (H+) and oxygen.

The Protons migrate through the membrane to be discharged on the cathode side where they react with oxygen in air, creating water vapor.

The membrane voltage can be reversed to change the direction of flow.

HOW TO SPECIFY

»     Consider the Humidity Level before and after use

               »     Determine the desired rate of water movement

               »     The saturation point of air is maximum level of water that it can carry (100%), and this is dependent on the temperature of the                       air.  Water densities in air are usually given in g/m³, and saturated air at 20ºC will hold 17.3g of water per m³, whereas at 40ºC it                       will hold 51.1g

               »     RH=actual water vapor density/saturation water vapor density x 100%

               »     From this equation it is possible to calculate any value given the other two.  For example, if the temperature is 20ºC and the RH                       is 57.8%, then the actual water vapor density is  57.8 x 17.3/100=10g/m³

HOW TO SPECIFY

Rates provided are for short-term use (i.e. first 100 hours), for longer-term use (i.e. many years) it is good to oversize the membrane by at least 25%, because after ‘initial operation’ performance can stabilize over time at lower than published rates.

Use the following table, select the appropriate membrane for the desired capacity
