Title:
DIRECT METHANOL-TYPE FUEL BATTERY SYSTEM AND PORTABLE ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2008/047632
Kind Code:
A1
Abstract:
This invention provides a fuel battery cell (1) comprising a fuel electrode (2), an electrolyte membrane (3), and an air electrode (4). The fuel electrode (2) and the air electrode (4) are electrically connected to each other by an electric circuit (L). A solid methanol storage vessel (5) as a fuel vessel is installed near the fuel electrode (2) side of the fuel battery cell (1). The storage vessel (5) comprises a solid methanol filled into a rectangular box-type casing (11). An opening part (12) as a gas permeable part is provided on the lower surface side. The opening part (12) is partitioned by a synthetic resin mesh (12A) formed of a permeable material to ensure the gas permeability in such a state that solid methanol has been held. The above constitution can provide a direct methanol-type fuel cell system in which, in a fuel cartridge state, a very safe solid methanol is used, and, even in the DMFC system, problems of liquid leakage and crossover involved in the use of a liquid fuel, can be solved, the feed speed of methanol can be regulated, and highly efficient power generation can be realized without causing a pressure rise in fuel electrode.
