Definitions for fuel cell
This page provides all possible meanings and translations of the word fuel cell
cell that produces electricity by oxidation of fuel (hydrogen and oxygen or zinc and air); often used in electric cars
An electrochemical device in which the intrinsic chemical free energy of fuel and oxidant is catalytically converted to direct current energy.
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen/air to sustain the chemical reaction, they can however produce electricity continually for as long as these inputs are supplied. In 1838, German Physicist Christian Friedrich Schönbein invented the first crude fuel cell. A year later Welsh Physicist William Grove developed his first crude fuel cells in 1839. The first commercial use of fuel cells was in NASA space programs to generate power for probes, satellites and space capsules. Since then, fuel cells have been used in many other applications. Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are used to power fuel cell vehicles, including automobiles, buses, forklifts, airplanes, boats, motorcycles and submarines. There are many types of fuel cells, but they all consist of an anode, a cathode and an electrolyte that allows charges to move between the two sides of the fuel cell. Electrons are drawn from the anode to the cathode through an external circuit, producing direct current electricity. As the main difference among fuel cell types is the electrolyte, fuel cells are classified by the type of electrolyte they use. Fuel cells come in a variety of sizes. Individual fuel cells produce relatively small electrical potentials, about 0.7 volts, so cells are "stacked", or placed in series, to increase the voltage and meet an application's requirements. In addition to electricity, fuel cells produce water, heat and, depending on the fuel source, very small amounts of nitrogen dioxide and other emissions. The energy efficiency of a fuel cell is generally between 40–60%, or up to 85% efficient if waste heat is captured for use.

Sample Sentences & Example Usage
There's a lot more room for the fuel-cell vehicle to improve and evolve.
One microbial fuel cell costs about 1 pound ($2) to make, and we think that a small unit like the demo we have mocked up for this experiment could cost as little as 600 pounds to set up, which is a significant bonus as this technology is, in theory, everlasting.
At Toyota, we believe that when good ideas are shared, great things can happen, the first generation hydrogen fuel cell vehicles, launched between 2015 and 2020, will be critical, requiring a concerted effort and unconventional collaboration between automakers, government regulators, academia and energy providers.
We were challenged by Oxfam to think about lighting urinals that they would use in refugee camps. So this is the result of that conversation. And it's basically a live trial to demonstrate the microbial fuel cell technology over a long period of time; how it can continuously generate electricity from urine in real time.
