Hydrogen
reformer for fuel cells |
This Argonne-developed reformer releases hydrogen from commonly available
fuels to power fuel cells in cars. Argonne's Shabbir Ahmed (left) explains
the reformer to U.S. Secretary of Energy Spencer Abraham and U.S. Rep.

Measuring fuel cell output |
A critical measure of a fuel cell's usefulness is its power output at
various electrical loads when supplying fuel (anode gas) and oxidant
(cathode gas) to the cell. A new fuel cell developed at Argonne, called
TuffCell, provides mechanical strength, easy fabrication and increased
performance. Argonne chemist Laura Miller prepares the TuffCell sample
for testing. Chemist Cecile Rossignol works in the background. Argonne

How
fuel cells work |
Argonne's fuel processor turns petroleum-based fuels, such as gasoline,
into hydrogen plus carbon monoxide and carbon dioxide. The carbon monoxide
is then converted into additional hydrogen plus sulfur and carbon dioxide
and the sulfur is removed, leaving only traces of carbon dioxide and
hydrogen. The hydrogen powers each of several fuel cells, which make
electricity to power the vehicle. The emissions are carbon dioxide and
a small amount of water. Argonne National Laboratory image.

Future hydrogen source |
Ceramic membranes
could supply hydrogen for energy applications, according to Argonne scientist
Balu Balachandran, leader of the group developing the new materials.
