What New Fibre Laser Welding Techniques Can Do

A fuel cell is an electro chemical energy conversion device, which produces electricity from external supplies of fuel (on the anode side) and oxidant (on the cathode side). These react in the presence of an electrolyte to produce energy. Since a typical fuel cell produces less than one volt, in practical application cells are 'stacked' in parallel to create a useful voltage.  Thus a typical fue...
