Electrolytic Cell - Definition, Diagram, Working, ... - BYJU''S
The extent of chemical change that occurs in an electrolytic cell is stoichiometrically related to the number of moles of electrons that pass through the cell. From the perspective of the voltage source and circuit outside the electrodes, the flow of electrons is generally described in terms of electrical current using the SI units of coulombs and amperes.
4: How Cells Obtain Energy
A galvanic cell (voltaic cell), named after Luigi Galvani (Alessandro Volta), is an electrochemical cell that generates electrical energy from spontaneous redox reactions. A wire connects two different metals (e.g. zinc and copper). Each metal is in a separate solution; often the aqueous sulphate or nitrate forms of the metal, howe…
15.2.4. Fuel cell efficiency. When comparing a fuel cell to a thermal engine for the production of electrical energy, it should be noted that the conversion yield is significantly higher in a fuel cell. In effect, the maximum theoretical efficiency of a thermal engine is given by the Carnot''s theorem: [15.18] ε thermal = W r (− Δ H) = 1 − T c T h ΔH …
