ABSTRACT:
A fuel gas reformer assemblage for use in a fuel cell power plant is formed from a composite plate assembly which includes spaced-apart divider plates with interposed columns of individual fuel gas and burner gas passages. The fuel gas passages are provided with walls which are wash coated with a catalyzed alumina complex. The catalyst complex includes a nickel catalyst and a cerium and/or lanthanum oxide component which stabilizes the alumina against recrystalization in the catalyst complex. The catalyst complex also includes a calcium oxide component which inhibits carbon formation on the alumina surface. The cerium or lanthanum oxide and calcium oxide combine to provide a synergistic improvement in both alumina stabilization and also in inhibition of carbon deposits on the washcoated surfaces.
