a Welsh judge and physical scientist. He anticipated the general theory of the conservation of energy, and was a pioneer of fuel cell technology. He invented the Grove voltaic cell. In 1839, Grove developed a novel form of electric cell, the Grove cell, which used zinc and platinum electrodes exposed to two acids and separated by a porous ceramic pot. Grove announced the latter development to the Académie des Sciences in Paris in 1839. In 1840 Grove invented one of the first incandescent electric lights, which was later perfected by Thomas Edison. Later that year he gave another account of his development at the British Association for the Advancement of Science meeting in Birmingham, where it aroused the interest of Michael Faraday. On Faraday's invitation Grove presented his discoveries at the prestigious Royal Institution Friday Discourse on 13 March 1840.
