What is a fuel cell electric vehicle? FCEVs use a propulsion system similar to that of electric vehicles, where energy stored as hydrogen is converted to electricity by the fuel cell. Unlike conventional internal combustion engine vehicles, these vehicles produce no harmful tailpipe emissions. Other benefits include increasing U.S. energy resiliency through diversity and strengthening the economy.
A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a polymer electrolyte membrane fuel cell, a catalyst separates hydrogen atoms into protons and electrons, which take ...
Honda began fundamental research on fuel cell technologies in the second half of the 1980s and developed a prototype fuel cell vehicle equipped with a 20kW fuel cell system in 1998. Honda kept making steady technological advancements to further improve the performance of its fuel cells, including the high efficiency and high output, and ...
16 de dic. de 2020 · A fuel cell “stack” combines the stored hydrogen with oxygen from the air, and a chemical reaction that produces electric current, and water, which drops out of a hidden vent pipe beneath the car. The fuel cell is composed of an anode, a cathode, and an electrolyte membrane. Hydrogen is passed through the anode, and oxygen through the cathode.
12 de ene. de 2012 · 1 INTRODUCTION Low-temperature proton exchange membrane fuel cells (PEMFC) afford the high-energy densities and fast start-up times required for automotive applications for low-carbon technologies [ 1 ]. PEMFCs fuelled by hydrogen generate electricity with the only local by-products being water and heat.
A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat. Fuel cells are unique in terms of the variety of their potential applications; they can use a wide range of fuels and feedstocks and can provide power for systems as large as a utility power station and as ...
