English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry.. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.
In 2022, the global fuel cell market was estimated to be $6.3 billion, and is expected to increase by 19.9% by 2030. [13] Many countries are attempting to enter the market by setting renewable energy GW goals. [14]
The Indian Certificate of Secondary Education (ICSE) is a certificate awarded upon satisfactory result in an examination conducted by the Council for the Indian School Certificate Examinations, a private board designed to provide an examination in a course of general education, in accordance with the recommendations of the New Education Policy 2020 (), through the medium of English.
The Council for the Indian School Certificate Examinations (CISCE) [1] is a non-governmental privately held national-level [2] [3] board of school education in India that conducts the Indian Certificate of Secondary Education (ICSE) Examination for Class X and the Indian School Certificate (ISC) for Class XII.

The upper graph shows the current density as function of the overpotential η . The anodic and cathodic current densities are shown as j a and j c, respectively for α=α a =α c =0.5 and j 0 =1mAcm −2 (close to values for platinum and palladium).
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
The first generally accepted theory of ET was developed by Rudolph A. Marcus (Nobel Prize in Chemistry in 1992) [8] to address outer-sphere electron transfer and was based on a transition-state theory approach. The Marcus theory of electron transfer was then extended to include inner-sphere electron transfer by Noel Hush and Marcus.
