A fuel delivery apparatus for a direct liquid feed fuel cell is provided. The fuel delivery apparatus includes a plate stack formed by a one or more double-sided plates positioned between opposing end plates. Both sides of the one or more double-sided plates, and the interior side of each end plate, may include one or more microchannels that extend between, and link, an inlet port with an outlet port. The length of the microchannels is chosen to be less than the height of a predetermined meniscus so that liquid fuel propelled by capillary force forms a meniscus that stands proximate the interface between the ends of the microchannels and the outlet port. A heater may be located at the upper ends of the microchannels around the plate stack, to vaporize the liquid fuel at the meniscus.
