A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a polymer electrolyte membrane fuel cell, a catalyst separates hydrogen atoms into protons and electrons, which take
Electricity (ELC) is the fuel, which has an associated final demand.The technologies are the following: photovoltaic power plants (PV), floating offshore wind turbines (WT), electrolyser (ELY), fuel cell (FC), and battery technology (BATT t).Two different storages were considered: the hydrogen tank (HT) and the battery storage
