Faraday efficiency and energetic efficiency of a PEM electrolyser

Article no: P9516600

Principle

The efficiency of an electrolyser is an indicator of the efficiency of energy conversion. A differentiation is made here between energetic and faradic efficiencies.

When a new technology is developed, it is important that it can be economically utilized. If the efficiency is low, then there is no sense in bringing it to market.

Different efficiencies of the electrolyser are examined in this experiment.
