Abstract

A die-cut wick for use in the burner of a disposable fuel cell formed from a single sheet of wicking material so that the wick has two symmetrical half-sections situated on either side of a vertical center line and which are folded along the center line into a face-to-face alignment. Each half-section further includes an elongated lower body segment containing a horizontally-disposed upper edge, a narrow neck segment centered on the upper edge of the body segment and a tab vertically extending therefrom to a given height. The neck is slidably received within a burner of a fuel cell so that it can be raised or lowered between limits to control the flame height and the amount of heat produced by the burner. The tabs are foldable toward and away from each other to further control the flame geometry and distribution of the heat.
