Faraday Efficiency (FE): Definition and Calculation for Gas Products

Faraday efficiency (FE) is a measure of the efficiency of an electrochemical process, representing the percentage of actual product generated compared to the theoretical product. For gas products, Faraday efficiency is calculated using equation (2). This equation quantifies the ratio of the actual amount of gas produced to the theoretical amount that should be produced based on the Faraday's law of electrolysis. Understanding Faraday efficiency is crucial for optimizing electrochemical processes and maximizing product yield.
