Abstract

The invention provides a fuel supplying device, comprising a first fuel supplier (1) and a second fuel supplier (2), wherein the fuel supplying device also comprises a channel (3) which has the length of between 5 and 300 millimeters and the ratio of the length to the cross-sectional area being between 150 and 600, and the first fuel supplier (1) and the second fuel supplier (2) are communicated by the channel (3). The invention also provides a passive type fuel battery with the fuel supplying device. In the fuel supplying device, the channel (3) communicated with the first supplier (2) and the second supplier (3) is slightly affected by the impurities in the fuel, thereby prolonging the service life of the fuel supplying device and improving the reliability of the fuel supplying device as well as prolonging the service life of the passive type fuel battery and improving the reliability of the passive fuel battery with the fuel supplying device. In addition, the fuel supplying device and the passive type fuel battery are easy to implement and have very important significance on the organic fuel battery of small-sized electronic products.

Description

technical field [0001] The invention relates to a fuel supply device and a fuel cell including the fuel supply device. Background technique [0002] A fuel cell is a device that directly converts chemical energy into electrical energy. It has the characteristics of high efficiency, less pollution and low noise. Existing fuel cells generally include an anode, a cathode, a proton exchange membrane between the anode and the cathode, and a fuel supply device. [0003] Taking the fuel as methanol and the oxidant as air or oxygen as an example, the battery undergoes the following electrochemical reactions: [0004] The following electrochemical reactions occur at the anode: [0005] CH 3 OH+H 2 O→CO 2 +6H + +6e (1) [0006] At the same time, the following electrochemical reactions take place at the cathode: [0007] 3 / 2O 2 +6H + +6e→3H 2 O, (2) [0008] Overall response: [0009] CH 3 OH+3 / 2O 2 →CO 2 +2H 2 O (3) [0010] The above-mentioned electrochemical reacti...
