How Fuel Cells Compare Understanding the primary technology powering vehicles is the first step to evaluating different vehicle types. Battery electric, hydrogen fuel cell electric, and internal combustion vehicles are each powered by a fundamentally different technology: Battery electric vehicles are powered by rechargeable batteries Fuel cell electric vehicles rely primarily on fuel cells Internal combustion vehicles burn fuel Rechargeable batteries, fuel cells, and combustion engines are distinct technologies, yet they share some common attributes.

Here is how fuel cells are similar to and different from rechargeable batteries and combustion engines: Fuel cells and batteries are devices that transform chemical energy from a substance or compound into electricity through electrochemistry. The electrochemical reactions in batteries and fuel cells are controlled and produce virtually zero pollutants.

The difference between the two technologies lies in the storage of fuel. A battery converts a finite amount of a chemical compound stored internally into electricity.

The chemical substance consumed in the battery to produce electricity is regenerated when the battery is recharged. A fuel cell, on the other hand, converts a chemical compound stored externally into electricity. That chemical compound is hydrogen stored in a tank onboard the FCEV.

Fuel Cell Versus Combustion Engines Fuel cells and combustion engines both consume fuel that is stored externally in a tank onboard the vehicle. Unlike the controlled chemical reactions in batteries and fuel cells, gasoline combustion is marked by a series of uncontrolled chemical reactions that produce many undesired compounds.

NOx, SOx, and particulate emissions are all undesired products of combustion that negatively affect air quality. The uncontrolled combustion of gasoline also reduces how efficiently engines transform chemical energy into power.

Therefore, a fuel cell electric vehicle is potentially 3 times as efficient as traditional combustion vehicle and virtually pollution-free. Fuel cell electric vehicles achieve the beneficial characteristics of both conventional and battery electric vehicles.

The combination of these desirable characteristics makes fuel cell electric vehicles an attractive advanced vehicle option for drivers that value long range, fast refueling, and zero-emissions.

The similarities and differences between conventional, battery electric, and fuel cell electric vehicles are summarized the figure below. Since current leasing packages for FCEVs include fuel, service and maintenance, physical damage insurance, in addition to all of the other perks and benefits you get from driving a FCEV, these cars may make sense—not just for the environment, but for your pocketbook.

Search incentives by zip code to find out what is available in your area. As for the cost of fuel, the standards for measuring dispensed hydrogen fuel for sale in California are under development, but do not exist today.

Although FCEV drivers have access to hydrogen fueling stations around the state, drivers are not paying for the fuel based on the amount dispensed. The cost of providing fuel is packaged as an add-on in vehicle lease agreements.

The state of California is aiming to sell hydrogen in the retail market before Check out the incentives search to find other incentives in your region. Fueling Most new hydrogen fueling stations are being located at existing gasoline stations, which means that hydrogen dispensers may be placed adjacent to or on the same island as the gasoline dispenser.2 Alternative Sources of Energy—An Introduction to Fuel Cells hydrogen ions electrons oxygen water and heat hydrogen electrons 2H 2.

Hydrogen fuel cells to power vehicles are desirable, experts say, because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power, and when pure hydrogen is used, the only emission from the tailpipe is harmless water vapor. An Introduction To Hydrogen Fuel Cells 1. Hydrogen as a FuelLow Carbon: Innovation, Opportunities and Training Presented by: Dirk Kok 2. AgendaAn Urgent Case. A hydrogen fuel cell electric vehicle is powered by a group of individual fuel cells, known as a fuel cell regardbouddhiste.com stack is designed to contain enough cells to provide .

Home» 5 Fast Facts about Hydrogen and Fuel Cells. Energy By The Numbers: Fuel Cell Electric Vehicles Compared to conventional gasoline vehicles, fuel cell vehicles can even reduce carbon dioxide by up to half if the hydrogen is produced by natural gas and by 90%, if the hydrogen is produced by renewable energy, such as wind and solar.

Fuel cells generate electricity by an electrochemical reaction in which oxygen and a hydrogen-rich fuel combine to form water. Unlike internal combustion engines, the fuel is not combusted, the energy instead being released electrocatalytically. A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity.

The other electrochemical device that we are all familiar with is the battery. A battery has all of its chemicals stored inside, and it converts those chemicals into electricity too.
