PURPOSE:To aim at improvement in the operatability of liquid fuel as well as the promotion of miniaturization and lightness of a cell, by making the liquid fuel turn into a state of non-liquidity through a physical or chemical means. CONSTITUTION:In this invention, methanol, formic acid, formalin or hydrazine, etc., are used by way of example, as the liquid fuel to be used, so that these fuel elements may be turned to a state of non-liquidity, there is a method that uses an adsorbent. As the adsorbent, for example, dextrin, dextran, cilica gel, an active carbon, etc., can be used. In addition, there are some chemical methods such that formic acid is converted into sodium formate, hydrazine into hydrazinium sulfate, and methanol into sodium methylate respectively, and furthermore formaldehyde is converted into paraformaldehyde after being polymerized. Doing like this, if a fuel element 1 being turned to a state of non-liquidity is held in a cartridge body 2 and formed into a cartridge type, operation for attaching/detaching the fuel element to/from a fuel cell becomes very simple. |
