NOVELTY - An impurity scavenger is held in a filter cartridge, outlet tube (248) or one of porous internal compartment in a liquid fuel container (242). The scavenger has a substance which removes impurity in liquid fuel.    USE - For liquid fuel cell used to generate electric power and reaction products, in portable electronic devices e.g. cell phones.    ADVANTAGE - The container controllably holds and delivers fuel to liquid fuel cell, regardless of its orientation.    DETAILED DESCRIPTION - An impurity scavenger is held in a filter cartridge, outlet tube (248) or one of porous internal compartment in a liquid fuel container (242). The scavenger has a substance which removes impurity in liquid fuel. The container with rectangular or square cross-section, has a fuel outlet with two-way valve, connected with a pump. A slidable solid wicking structure (244) with a volume more than 50%, not more than 40%, less than 20%, less than 10%, not more than 5%, not more than 3%, or 1% of that of container, is held in required orientation by a connector in a perforated or slotted retainer in the container, to receive liquid fuel by capillary action. The solid volume of the retainer, is 5% or 1% of the container volume. The wicking structure contacts specific portion of the container walls. The retainer is attached to a cap engaging with distal end of the container. The connector is a clamp, combination of clamps, toothed edge or VELCRO (RTM) nub. The wicking structure made of foams, bundled fibers, matted fibers, non-woven fibers, woven fibers, needled fibers, porous polymers, Porex or inorganic porous materials, is connected to container by heat sealing, ultrasonic welding, adhesive or injection molding process. The polyurethane foam has a density of 0.5-45 pounds or 0.5-25 pounds or 0.5-10 pounds or 1.5-60 pounds per cubic foot and pore size in the range of 10-200 pores or 40-200 pores or 75-200 pores per linear inch. The container inlet tube (250) has an one-way valve (251). The cap has a membrane through which fuel is supplied. The central portion free of wicking portion, has a volume of 70%,80%,90% or 95% of the container volume. The scavenger has activated carbon, amorphous carbon, silica, silicate, activated charcoal, graphite powders, expanded graphite, aluminosilicate, diatomaceous earth, Celatom FW80, exchange resins, zeolite, molecular sieves or filter agents. The ingestion deterrent is ipecac.    An INDEPENDENT CLAIM is also included for dispensing method of liquid fuel from container to liquid fuel cell or modifier involves supplying liquid fuel comprising ingestion deterrent and/or flame brightener.
