Fuel Cells – Overview and Classification of Fuel Cells
The fuel cell

The first to discover the principle of fuel cells was the Englishman Sir William Grove (1811~1896), a lawyer and amateur science enthusiast. In an accidental electrolysis experiment in 1839 [Fig. 1(a)], it was observed that when two electrodes in an electrolyzer were connected together [Fig. 1(b)], a current flowed in the opposite direction, consuming both … Read More “Fuel Cells – Overview and Classification of Fuel Cells” »
