Fuel container and delivery apparatus for a liquid feed fuel cell system

An effluent container for use with a fuel cell system, comprising:

• (A) a fuel cell in which reactions occur to produce electricity, and such reactions producing effluent;
• (B) an outer container;
• and
• (C) an inner bladder for receiving effluent from said fuel cell through an effluent inlet leading from said fuel cell into said container.

A method of delivering fuel to and removing effluent from a fuel cell in a fuel cell system, including the steps of:

• (A) providing a direct oxidation fuel cell including a membrane electrode assembly;
• (B) coupling a container with said fuel cell, including:
• (i) providing within said container, a first inner bladder being substantially fully expanded upon being filled with liquid fuel, and having a fuel outlet conduit to supply liquid fuel to said direct oxidation fuel cell;
• and
• (ii) providing within said container, a second inner bladder for receiving effluent from said fuel cell through an effluent inlet leading from said fuel cell into said container as reactions occur in said fuel cell, in such a manner that as effluent enters said second inner bladder, said second inner bladder expands and contacts said first inner bladder and displaces fuel out of said first inner bladder to said fuel cell.
