Hydrogen power generation system with air humidity adjusting function

Abstract

The invention discloses a hydrogen power generation system with an air humidity adjusting function. The hydrogen power generation system comprises a fuel battery and further comprises an air humidity control device and an air pump, wherein the air humidity control device is provided with a containing space; the air humidity of the containing space is 75%-90%; an air humidity adjusting pipeline is mounted in the containing space and comprises a water-permeable and air-impermeable pipeline; and external air is driven by the air pump and passes through the air humidity adjusting pipeline to enter the fuel battery. According to the hydrogen power generation system, the humidity of the air entering the fuel battery can be adjusted to 75%-90% so that the starting efficiency of the fuel battery can reach standard efficiency in short time, and the working efficiency of the fuel battery reaches the highest level.

Description

technical field [0001] The invention relates to a hydrogen power generation system, in particular to a hydrogen power generation system with air humidity adjustment function. Background technique [0002] Hydrogen is one of the most ideal energy sources in the 21st century. When burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water without ash and waste gas. pollute the environment; while coal and oil combustion mainly produce CO 2 and SO 2 , which can produce the greenhouse effect and acid rain respectively. The reserves of coal and oil are limited, while hydrogen is mainly stored in water, and the only product after combustion is water, which can continuously produce hydrogen and never run out. The distribution of hydrogen is very wide, and water is a large "warehouse" of hydrogen, which contains 11% hydrogen. There is about 1.5% hydrogen in soil; oil, coal, natural gas, animals and plants ...

AI Technical Summary

Problems solved by technology

In addition, when the air humidity is too low when the fuel cell is started, the starting performance will be far worse than the baseline performance, resulting in a rather long starting time to reach the maximum rated power (compared to the normal starting time of 10 to 20 seconds to reach the maximum power, Battery pack may take up to 3 minutes to reach full power)

However, in the prior art, since the outside air directly enters the fuel cell, the humidity of the outside air varies greatly. If it is cloudy and rainy, the humidity of the outside air can reach more than 60%, but if it is sunny or in winter in the north, then The air humidity is very low, even less than 10%, which will seriously affect the performance of the fuel cell, thereby affecting the work of loads (such as mobile communication base stations)
