Fuel cells are electrochemical devices, so they are not constrained by the maximum thermal (Carnot) efficiency as combustion engines are. Consequently, they can have very high efficiencies in convertingchemical energytoelectrical energy. In the archetypal example of ahydrogen/oxygenproton-exchange membran...
The requirements on electron and fuel cells is related to the locations of energy and ion conduction in electrodes and the electrolyte storage and conversion. Batteries are closed systems, are given in Figure 1 and are valid for all three with the anode and cathode being the charge-transfer ...
Step-by-Step Solution:1. Definition of Fuel Cells: Fuel cells are electrochemical devices that convert the chemical energy of fuels, such as hydrogen, carbon monoxide, or methane, directly into electrical en
