Carnot versus electrochemistry : This essay critically compares the advantages and disadvantages of Carnot‐cycle‐based and electrochemical methods for the generation and storage of energy (see picture; left: PEM fuel cell; right: Au(111) model surface covered with 0.025 monolayers of Pt). The views of Wilhelm Ostwald (1853–1932) and today's understanding of energy conversion are contrasted.
