A fuel cell assembly is disclosed that utilizes a water transport structure extending from fuel cell plates of the assembly into fuel cell assembly manifolds, wherein the water transport structure facilitates the transport of liquid water from the fuel cell plates thereby minimizing the accumulation of liquid water and ice in the fuel cell stack. The bus state controller includes control registers such as wait controllers, and parallelly controls the interfaces of various semiconductor memories and PC cards. The motor is supported by the housing and driven by alternate-current power.
