Abstract
A fuel cell and mold therefor, which fuel cell is characterized by a molded plastic fuel container having a fuel pick-up opening in the top thereof and a molded wedge provided in the bottom thereof in angular relationship, which molded wedge serves to isolate and accumulate small quantities of fuel when the fuel cell is almost empty, to facilitate more efficient retrieval of fuel from the fuel cell. The fuel cell is molded inside a two-piece mold provided with mating flanges and a wedge blade slot is shaped in the bottom mold section for receiving a removable wedge insert blade designed to shape the molded wedge in the fuel cell. The mold is charged with a plastic powder and catalyst mixture and is attached to a rotating apparatus to effect simultaneous rotation on two axes while heated, to melt the plastic powder and shape the fuel cell.
