Abstract
A catalyst support comprises a stack of metal strips, said strips being coated with a catalyst material. Indentations in the strips maintain uniform spacing between the strips, so that gas can flow between the strips. The indentations are spaced so that the indentations in adjacent strips cannot coincide and nest together, so that adjacent strips cannot collapse together.
