Similar to conventional internal combustion engine vehicles, they can fuel in\u00a0less than 5 minutes and have a driving range over 480 kilometres. FCEVs are equipped with other advanced technologies to increase efficiency, such as regenerative braking systems, which capture the energy lost during braking and store it in a battery. Major automobile manufacturers are offering a limited but growing number of production FCEVs\u00a0to the public in certain markets, in sync with what the developing infrastructure can support.<\/span><\/p>\n<h3><strong><span style=\"color: #000000;font-size: 14pt\">How Fuel Cells Work<\/span><\/strong><\/h3>\n<p><span style=\"color: #000000;font-size: 12pt\">The most common type of fuel cell for vehicle applications is the polymer electrolyte membrane (PEM) fuel cell. In a PEM fuel cell, an electrolyte membrane is sandwiched between a positive electrode (cathode) and a negative electrode (anode). Hydrogen is introduced to the anode, and oxygen (from air) is introduced to the cathode. The hydrogen molecules break apart into protons and electrons due to an electrochemical reaction in the fuel cell catalyst. Protons then travel through the membrane to the cathode.<\/span><\/p>\n<p><span style=\"color: #000000;font-size: 12pt\">The electrons are forced to travel through an external circuit to perform work (providing power to the electric car) then recombine with the protons on the cathode side, where the protons, electrons, and oxygen molecules combine to form water.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>Source: afdc.energy.gov<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fuel cell electric vehicles (FCEVs) are\u00a0powered by hydrogen.
