1. A fuel supply for a fuel cell, comprising:

  • a liquid storage area that includes a liquid reactant;

    a reaction area that includes a solid reactant, wherein the liquid reactant is pumped into the reaction area such that the liquid reactant reacts with the solid reactant to produce reaction components;

    a product collection area that receives the reaction components;

    a barrier that separates the liquid storage area from the product collection area and moves to simultaneously increase the product collector area and decrease the liquid storage area as the liquid reactant is pumped from the liquid storage area and the reaction components are transferred into the product collection area; and

    a container with an interior volume that substantially encloses the reaction area, liquid storage area, and product collection area;

    wherein the product collection area is fluidly coupled to the reaction area by the flexible channel and includes a product filter that adsorbs the liquid and solid components; and

    wherein the product filter comprises of a series of open-cell foams with different pore sizes, wherein the pore sizes of the foams decrease with increasing distance from the flexible channel.
