The processes that take place during the discharging of a lead–acid cell are shown in schematic/equation form in Fig. 3.1A can be seen that the HSO 4 − ions migrate to the negative electrode and react with the lead to produce PbSO 4 and H + ions. This reaction releases two electrons and thereby gives rise to an excess of negative charge on the electrode …
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.
