Patent ID: 7306781

Claim:
A method of making hydrogen, comprising: a) directing a hydrocarbon fuel into a combustion region of a monolith formed by folding a corrugated strip back and forth upon itself to define a plurality of fluid flow regions, said plurality of fluid flow regions comprising a first fluid flow regions, second fluid flow region and a third fluid flow region, said first, second and third fluid flow regions being different fluid flow regions, said first fluid flow region defining the combustion region, the combustion region having a combustion catalyst, b) directing a hydrocarbon fuel into said second fluid flow region which defines a steam reforming region, the steam reforming region having a steam reforming catalyst, c) directing a stream of water into said third fluid flow region, while directing products of the combustion region so as to be in heat exchange relationship with said stream of water, so as to produce steam, and d) withdrawing hydrogen from said steam reforming region.
