Proton Exchange Membrane Fuel Cell
Proton exchange membrane fuel cells, also known as polymer electrolyte membrane (PEM) fuel cells (PEMFC), are a type of fuel cell being developed for transport applications as well as for stationary fuel cell applications and portable fuel cell applications. Their distinguishing features include lower temperature/pressure ranges (50 to 100 °C) and a special polymer electrolyte membrane. They are a leading candidate to replace the aging alkaline fuel cell technology, which was used in the Space Shuttle.

Famous quotes containing the words exchange, fuel and/or cell:
“I know nothing which life has to offer so satisfying as the profound good understanding, which can subsist, after much exchange of good offices, between two virtuous men, each of whom is sure of himself, and sure of his friend. It is a happiness which postpones all other gratifications, and makes politics, and commerce, and churches, cheap.”
—Ralph Waldo Emerson (1803–1882)
“It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world, the prince and the peasant, the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food. Neither could I do without them.”
—Henry David Thoreau (1817–1862)
“In America all too few blows are struck into flesh. We kill the spirit here, we are experts at that. We use psychic bullets and kill each other cell by cell.”
—Norman Mailer (b. 1923)
