A detachable independently sealed fuel battery

The invention discloses a separated independent sealing fuel cell, including a gas guide plate and a membrane electrode assembly; part of a sealing area of the membrane electrode assembly is composed of a proton exchange membrane by extending to the periphery; a first sealing ring is arranged on the gas guide plate around the active area, a second sealing ring is arranged around the non-active area, a buffer area is arranged between the first sealing ring and the second sealing ring on the gas guide plate for isolating the first sealing ring and the second sealing ring, and the sealing area of the membrane electrode assembly is corresponding to the sealing area of the first sealing ring and is extruded by the first sealing ring. The fuel cell has superior sealing performance.
