1. A method of manufacturing an annular recuperator for a gas turbine engine comprising the steps of;stamping a plurality of spaced integral ribs on a first metal plate so as to partially define a plurality of high pressure channels; stamping a plurality of spaced integral ribs on a second metal plate so as to partially define a plurality of low pressure channels; joining said first and second metal plates to form a cell wherein said high pressure channels are fully defined and disposed internally thereof; assembling said cells in an annular array with the first and second metal plates thereof, respectively, in juxtaposed relation so as to define said low pressure channels; and joining only a radially inner edge portion of said cells to one another.
