Abstract

The invention relates to a direct methanol fuel battery system of a concentration-exempted detector, which comprises a plurality of fuel batteries, a circulating fuel groove with an air exhausting device, at least one control component, a circulating pump, an air circulating fan, a fuel feeder, and an alarm device which is connected to the control component, wherein, the control component comprises at least over one control circuit board, an IC chip or an electronic component. When the IC chip on the control circuit board detects that the voltage is lower than some lower limit value, the alarm device can be activated for warning users or operators to feed fuel to the circulating fuel groove by the fuel feeder. The direct methanol fuel battery system of the concentration-exempted detector provided by the invention is matched with a fuel injection port which is designed specifically according to the phenomena that methanol liquid is hard to carry and prevent leakage. The invention does not need a concentration detector, but needs a methanol water solution circulating groove, and has the advantages of system volume conservation and cost conservation.

Description

technical field [0001] The present invention relates to a direct methanol fuel cell system, in particular to a direct methanol fuel cell system without a concentration detection device. Background technique [0002] As those familiar with this technology know, direct methanol fuel cells need to use a certain concentration of fuel, and when the fuel cell continues to operate, the concentration of fuel in the circulating fuel tank will gradually decrease over time, and eventually it will not work. Therefore, it is necessary to continuously add fuel to make the fuel cell continue to operate. [0003] However, the amount and concentration of fuel to be added depends on the concentration of methanol water in the fuel tank. Therefore, the known direct methanol fuel cell needs a set of concentration detection devices to detect the concentration of fuel to detect the methanol water in the fuel tank. Concentration, in order to determine the amount and concentration of added fuel. ...
