The power section includes a fuel cell stack.
The stack is a series of electrode plates connected to produce
the desired current and voltage power.
A lot of research is being done to develop
catalysts that are more tolerant to CO. At present the best anode
catalysts are Pt/Ru alloys supported on carbon.
|
| CO acts as a poison to the Pt based catalyst,
and must be removed, with a catalyst of Pt on alumina. When hydrogen
fuel is used, these units become unnecessary. |
| Hydrogen, though
the best fuel from a chemical point of view, is a hazardous gas
to store and transport, particularly for use in, for example, a
fuel cell powered vehicle. It is possible, however, to generate
hydrogen as needed from a liquid fuel such as methanol. This process
is called reforming. |
| Converts readily available methanol,
to a hydrogen-rich gas that is fed to a fuel cell. Catalyst: Pt
or Rh on a support of alumina, ceria, or zirconia, or a mixture
of these.
The reformate contains H2, CO2 and
traces of CO.
