NOVELTY - An electric fuel cell unit comprises two plates (12, 14) including an aperture(s) (24A, 24B, 25A, 25B, 26A, 26B, 28A, 28B), a first resilient sealing media (18) comprising a sealed channel between the plates, and a second resilient media (20) disposed about a non-facing side of one of the plates.    USE - The invention is used for generating electric power.    ADVANTAGE - The invention prevents leakage between adjacent fuel cell plates, and is highly reliable particularly in mass production manufacturing environments.    DETAILED DESCRIPTION - An electric fuel cell unit comprises:    (1) two plates aligned in spaced, parallel facing proximity with one another, each of the plates including an aperture(s) adapted for mating alignment with the other, where each the aperture of one plate is in alignment with the aperture of the other plate;    (2) a first resilient sealing media disposed over portions of each surfaces of the plates, the media extending through and from the apertures and adapted to comprise areas of separation of coolant fluid flows between the plates, and where each of the areas of separation comprises a sealed channel between the plates; and    (3) a second resilient media disposed about a non-facing side of one of the plates, the second resilient media having a thickness greater than the thickness of the first scaling media, where all of the media collectively comprises a unitary, contiguous mass of material passing through the apertures and extending between the plates.    An INDEPENDENT CLAIM is also included for a method of making an electrolytic fuel cell unit comprising:    (1) providing a pair of fuel cell plates aligned in spaced, parallel facing proximity with one another;    (2) placing the plates together in the alignment on the floor of a mold with a space between bottom plate and the floor;    (3) forcing liquid sealing media into the gating apertures under pressure;    (4) permitting the media to cure; and    (5) removing the fuel cell plates with the cured media from the mold.    DESCRIPTION OF DRAWING(S) - The figure shows an exploded view of the fuel cell unit.
