Abstract
The invention discloses a circular tube type microfluid fuel cell. The circular tube type microfluid fuel cell is structurally characterized in that a circular tube channel for cell electrochemical reaction is formed by combining two hollow cylinders with different sizes and fan-shaped sectional areas, concave through grooves are formed in the two sides of the left half part of the circular tube channel in the axial direction, bosses are arranged at the corresponding positions of the right half part of the circular tube channel, and the concave through grooves and the bosses are matched and assembled seamlessly; electrode grooves are symmetrically formed in the two semi-hollow cylinders respectively, and a porous negative electrode and a porous positive electrode are arranged in the grooves respectively; wire through holes are symmetrically formed in the bottom of each electrode groove, one end of each wire is connected with the porous electrode, and the other end of each wire is connected with a load; a Y-shaped three-way pipe is connected with the circular tube channel, and one pipeline of the Y-shaped three-way pipe is a fuel inlet, and another pipeline is an oxidant inlet; and the mixed fluid outlet end of the circular tube channel is connected with a liquid discharge tube; and therefore, the circular tube type microfluid fuel cell is formed. The Y-shaped three-way pipe is prepared through a 3D printing technology, so that the preparation complexity of the microfluid fuel cell is reduced, and the microfluid fuel cell can be conveniently and widely applied to small portable equipment.
Description
technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a circular tube microfluidic fuel cell. Background technique [0002] With the gradual deepening and integration of electronic science, Internet of Things, big data and other modern technology-related research, the number of indispensable portable electronic devices in various fields is also increasing. At present, all kinds of portable electronic devices are developing in the direction of miniaturization, integration and multi-function. Therefore, the energy supply devices of these devices must meet the requirements of portability, high energy density, and high energy efficiency in order to achieve the goals of low cost, long battery life, and stable operation. At present, lithium-ion batteries are widely used in portable electronic devices, but they have disadvantages such as low theoretical energy density, long charging time, narrow normal use temperature range...
