An ion electrospray device with a porous reservoir and at least one porous emitter includes a porous compliant interface sandwiched between the porous reservoir and the porous emitter for transferring fluid from the porous reservoir to the porous emitter. The interface has a characteristic capillary pressure stronger than the characteristic capillary pressure of the porous reservoir to fill the porous emitter with fluid via a fluid injection section of the interface and before the porous reservoir is then partially filled with fluid. Emitter leakage and propellant bridging problems are addressed.
