Fuel conversion to hydrogen is an important part of most fuel cell systems.
The paper describes the available technologies for conversion of hydrocarb
ons and alcohols. The endothermic steam reforming catalysts and processes a
s well as autothermal reforming are proven technologies. Recent development
s include catalytic partial oxidation. The integration of the fuel processi
ng with the fuel cell represents a task with requirements depending on each
type of fuel cell and application. The automotive use of fuel cells is at
present a special challenge. The optimum fuel for stationary plants is natu
ral gas (if available), whereas light naphtha appears to be the choice for
automotive use.
