Abstract: Method of manufacturing a deformable fuel cell embodying the steps of providing a flexible mold which has an opening therein. A nut ring secured to the periphery of the opening and a protective plate is attached to the nut ring. Coating material is applied to the mold which hardens to form a body. The protective plate is removed and the nut ring is detached from the mold. The mold is then collapsed and removed from the body through a hole in the nut ring. Ballistic nylon cloth may be applied to the mold before the application of the coating material.
