Problems solved by technology

However, this air supply mode has special requirements on the structure of the fuel cell stack. If the air without purification and filtration is directly used, it is easy to pollute the electrodes in the fuel cell stack; if pure oxygen is used, the bicycle itself must With its own oxygen storage tank, the amount of oxygen stored limits the driving distance of electric bicycles

Abstract

The invention discloses a direct alcohol fuel cell power generation system, which comprises a direct alcohol fuel cell pile, a fuel storage tank, a first fuel feeding pump, a starting module, a system control module, a starting power supply, an air compression pump, an air filtering device arranged between the air compression pump and the direct alcohol fuel cell pile, and a cathode water cooling recovery device used for recovering the cathode water of the direct alcohol fuel cell pile. The air compression pump provides air which contains an oxidant substance oxygen (O2) required by the reaction of the fuel cell pile to avoid the use of an oxygen storage tank; and therefore, compared with the prior art, the direct alcohol fuel cell power generation system is convenient to carry and stable in performance. In addition, the air filtering device arranged between the air compression pump and the direct alcohol fuel cell pile purifies the air, so that electrode pollution caused by the uncleanness of the air in the fuel cell pile is avoided.

Description

technical field [0001] The invention relates to the technical field of direct alcohol fuel cells, and more specifically relates to a direct alcohol fuel cell power generation system. Background technique [0002] In recent years, electric bicycles with the advantages of convenience, speed, and reasonable price have developed rapidly, and, along with the obvious improvement of the performance of batteries suitable for electric bicycles, electric bicycles will become an ideal means of transportation for people to travel. The core component of an electric bicycle is the battery, and the performance of the battery determines the performance of the electric bicycle. At present, the batteries suitable for electric bicycles on the market are mainly lead-acid batteries and lithium-ion batteries. Among them, lead-acid batteries have many disadvantages such as low mass energy density, long charging time, and easy to cause environmental pollution; large-capacity power lithium-ion batte...
