Elementary idea of atomic structure

Atomic structure In 1897 J.J. Thomson discovered electron as a constituent of atom. He determined that an electron had a negative charge and had very little mass as compared to that of the atom. Since an atom was found to be electrically neutral it was inferred that some source of positive charge must be present … Read more

Fuel Cells

What is a Fuel Cell? A fuel cell is an electrochemical device that converts chemical energy from a fuel into electrical energy and heat. Fuel cells are similar to batteries in that they both convert chemical energy into electrical energy, but fuel cells do not run down and need to be recharged. Instead, they can … Read more
