Portable power system

Abstract

The invention discloses a portable power system. A fuel output port of a double-port liquid storage tank is communicated with an inlet of a catalytic reactor, an outlet of the catalytic reactor is communicated with an inlet of a gas-liquid separator, a gas outlet of the gas-liquid separator is communicated with an anode inlet of a proton exchange membrane fuel cell through a hydrogen pipe, an anode outlet of the proton exchange membrane fuel cell is communicated with the inlet of the gas-liquid separator through a recovery pipe, a liquid outlet of the gas-liquid separator is communicated witha waste liquor reflux inlet of the double-port liquid storage tank through a waste liquor pipe, an air input pipe is communicated with a cathode inlet of the proton exchange membrane fuel cell, a cathode outlet of the proton exchange membrane fuel cell is communicated with an air output pipe, and a storage battery is connected with the proton exchange membrane fuel cell. The power system is smallin size, convenient to carry and higher in safety, energy density and utilization ratio.

Description

technical field [0001] The invention belongs to the technical field of hydrogen fuel cells and relates to a portable power supply system. Background technique [0002] With the improvement of people's living standards, more and more people go to the field for tourism or experience. Under normal circumstances, there is a lack of charging facilities in the wild environment. In order to ensure personal safety, travelers need to carry portable power sources with high energy density to ensure that their communication electronic equipment or other positioning electronic equipment can work normally and keep in touch with the outside world at all times. At present, most of the portable power sources are storage batteries, and its energy density is difficult to ensure that users stay in the field for a long time (such as more than three days). As a device that directly converts chemical energy into electrical energy, fuel cells have no mechanical parts, are quiet and noiseless, have...

Problems solved by technology

It not only increases the volume of the system virtually and complicates the system, but also makes the fuel remaining in the waste liquid not fully utilized, resulting in a certain degree of waste of fuel

[0004] At present, the existing fuel cell control systems on the market generally control the battery voltage directly by controlling the hydrogen supply, and the control method is single.

In addition, the general fuel cell power generation system directly discharges the mixture of hydrogen and water into the air, not only part of the unreacted hydrogen cannot be fully utilized, but also there is a hidden danger of hydrogen explosion, which reduces the safety performance of the system
