CSIR-National Physical Laboratory (CSIR-NPL), New Delhi, has developed low-cost Carbon Composites Bipolar Plates for Hydrogen-based Fuel Cell applications. Fuel cell is an electrochemical device that converts the chemical energy of the reactants (H2 and O2) directly into electricity & heat with high efficiency. The main components of PEM fuel cell are composite bipolar plate, porous carbon paper electrode, polymer electrolyte membrane and platinum catalyst. Carbon composites bipolar plate is a multi-functional component within the PEM fuel cell stack. It connects and separates the individual fuel cells in series to form a fuel cell stack with required voltage, its main function is uniform distribution of fuel gas and oxygen over the whole active surface area of the membrane electrode assemblies (MEA), conduct electrical current from the anode of one cell to the cathode of the next, facilitate water management within the cell, support thin membrane and electrodes and clamping forces for the stack assembly, among other things. The composites bipolar plates are light weight.
