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) to sustain the chemical reaction, whereas in a battery the chemical energy comes from ...
A proton exchange membrane fuel cell transforms the chemical energy liberated during the electrochemical reaction of hydrogen and oxygen to electrical energy, as opposed to the direct combustion of hydrogen and oxygen gases to produce thermal energy.. A stream of hydrogen is delivered to the anode side of the MEA. At the anode side it is catalytically split into protons and electrons.
Fuel Cell Basics. Through this website we are seeking historical materials relating to fuel cells. We have constructed the site to gather information from people already familiar with the technology–people such as inventors, researchers, manufacturers, electricians, and marketers.
Awaiting the arrival of the world's very first (FCV) fuel cell vehicle? You can test drive the technology of the future right now, with Fuel Cell Store's selection of fuel cell powered remote control cars.
A fuel cell is like a battery in that it generates electricity from an electrochemical reaction. Both batteries and fuel cells convert chemical potential energy into electrical energy and also, as a by-product of this process, into heat energy.
What are the Benefits of Fuel Cells? Environmental - Fuel Cells achieve high fuel efficiency while emitting extremely low emissions. Engineering - Fuel cells operate on a wide variety of fuels, utilize electrochemical reactions and contain no moving parts.
Power. Fuel cell-powered lift trucks are refueled in minutes, offering a highly productive alternative to the changing and recharging of lead acid batteries, plus a clean, emissions-free alternative to internal combustion engines.
In most cases hydrogen is the preferred fuel for use in the present generation of fuel cells being developed for commercial applications. Of all the potential sources of hydrogen, natural gas offers many advantages.
Cell - Coupled chemical reactions: Cells must obey the laws of chemistry and thermodynamics. When two molecules react with each other inside a cell, their atoms are rearranged, forming different molecules as reaction products and releasing or consuming energy in the process. Overall, chemical reactions occur only in one direction; that is, the final reaction product molecules cannot ...
Blue circles plot the rate of H 2 O 2 production in seawater. The blue circles show the rate of H 2 O 2 production in lab-mixed salt water, while the red squares indicate the rate of production in pure H 2 O. All of the mixtures had their pHs adjusted to 1.3 for this experiment, making them highly acidic and encouraging the redox reactions that charge a fuel cell.
