Hydrogen fuel cell technology

Why are hydrogen fuel cells so expensive? How does a hydrogen fuel cell engine work? A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent.

Fuel cells are different from batteries in requiring a continuous source of fuel and oxygen (usually from air). A fuel cell is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy.

A PEM (Proton Exchange Membrane) cell uses hydrogen gas (H 2) and oxygen gas (O 2) as fuel. The products of the reaction in the cell are water, electricity, and heat. Steam reforming of methane is a common method of hydrogen production today. It starts with liquids or gases containing hydrogen like natural gas or sustainable biogas sourced from landfills.

The fuel then reacts with steam at high temperatures in a reformer, leaving you with hydrogen. The byproduct of hydrogen combustion is usually just heat and water. With hydrogen as fuel , you eliminate the creation of air pollution and other toxic elements.

With that sai it does take energy to actually obtain the hydrogen fuel. Hydrogen and Fuel Cell Technology Basics. It is a major component of water, oil, natural gas , and all living matter. Despite its simplicity and abundance, hydrogen rarely occurs naturally as a gas on Earth. It is almost always combined with other elements.

It can be generated from oil, natural gas , and biomass or by splitting water using renewable solar or electrical energy. Today, hydrogen fuel cell test vehicles are already on the road. The result is an electric car with no emissions except water. Montage of homes, buildings, vehicles, and hydrogen fuel cell technology. Similar to today’s gasoline vehicles, fuel cell electric cars can have a driving range of more than 3miles on one tank of hydrogen fuel.

They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. The Fuel Cell Technologies Office (FCTO) focuses on applied research, development, and innovation to advance hydrogen and fuel cells for transportation and diverse applications enabling energy security, resiliency, and a strong domestic economy in emerging technologies. One great appeal of fuel cells is that they generate electricity with very little pollution–much of the hydrogen and oxygen used in generating electricity ultimately combine to form a harmless byproduct, namely water. 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. The stack is designed to contain enough cells to provide the necessary power for the automotive application. A fuel cell stack produces power as long as fuel is available, similar to a combustion engine. Fuel Cell Technology Fuel cells are emerging as a leading alternative technology to replace more polluting ICEs in vehicle, marine, and stationary distributed energy applications.

There are a handful of different fuel cell technologies and fuels being considered for these applications. The operation of the hydrogen fuel cells is similar to that of a battery. The hydrogen fuel cell has two electrodes - an anode and a cathode, which are separated by a membrane. Oxygen passes over the cathode, and hydrogen passes over the anode.

Energy can be efficiently utilize without waste. No, water vapor is the natural—and only—byproduct of fuel cell technology. The Clarity Fuel Cell can, however, run on hydrogen that is created by electrolyzing water using renewable electricity.

Mirai is the first mass production hydrogen Fuel Cell Electric Vehicle. Powered by hydrogen , it enables you to enjoy silent, responsive, long distance, zero CO emissions driving - while only emitting water from the tailpipe. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car.
