Embodiment 1

[0034] see figure 1 , the present invention provides a technical solution: a high-efficiency purging system for fuel cells, including an air supply module A0, a hydrogen supply module H0, a heat dissipation module W0, and a PEMFC1 fuel cell. The air supply module A0 includes an air filter A5, an air compressor A3, air inlet valve A4, air outlet valve A1, bypass valve A2, back purge valve A6, purge and relief valve A7, air inlet pressure sensor P3, outlet pressure sensor P4 and interconnected pipelines, hydrogen supply module H0 includes hydrogen tank TK1, bottle mouth valve H1, hydrogen pressure regulating valve H2, hydrogen flow controller H3, hydrogen circulation pump H4, gas-liquid separator H5, hydrogen pipeline discharge valve H6, hydrogen inlet pressure gauge P1, hydrogen outlet The pressure gauge P2 is composed of interconnected pipelines. The heat dissipation module W0 includes a three-way regulating valve W1, a radiator W2, a coolant circulation pump W3, a coolant out...

Embodiment 2

[0040] see figure 2 , 4 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a control method for a high-efficiency purge system of a fuel cell, comprising the following steps:

[0041] Step 1: First, S10 judges whether the fuel cell sends out a stop signal, that is, whether the operation switch is closed. If there is no stop signal, S10 is no, then end this control, and if the stop signal is received, S10 is yes, then proceed to S20 control;

[0042] Step 2: Run forward purge, keep compressor A3 running at this time, the specific operating speed is determined according to the test, and open valves A4, A1, close A2, A6, A7, and judge in S30 whether the purge duration is Reach Tn, this time is determined by experiment;

[0043] Step 3: If the judgment result of S30 is yes, stop the forward purge and stop the operation of compressor A3;

[0044] Step 4: Enter S50 to judge whether the difference between P3 and P4 is less than P0+a, wher...

Abstract

The invention discloses an efficient fuel cell purging system and a control method thereof, relates to the field of auxiliary devices for rehabilitation medicine, solves the problems that water accumulated nearby a gas flow path in the gas flow path in an existing fuel cell cannot be completely discharged, and the purging efficiency is relatively low, and provides the following scheme. The system comprises an air supply module A0, a hydrogen supply module H0, a heat dissipation module W0 and a PEMFC1 fuel cell, the air supply module A0 comprises an air filter A5, an air compressor A3, an air inlet valve A4, an air outlet valve A1, a bypass valve A2, a reverse purging valve A6, a purging release valve A7, an air inlet pressure sensor P3, an outlet pressure sensor P4 and mutual connection pipelines, the hydrogen supply module H0 comprises a hydrogen tank TK1, a bottleneck valve H1, a hydrogen pressure regulating valve H2, a hydrogen flow controller H3 and a hydrogen circulating pump H4. The device can efficiently and comprehensively purge and drain water, and the reaction output efficiency of the fuel cell is improved.

Description

technical field [0001] The invention relates to the field of auxiliary devices for rehabilitation medicine, in particular to a fuel cell high-efficiency purging system and a control method thereof. Background technique [0002] A fuel cell is a fuel and an oxidant that contain certain other [0003] It is a device that directly converts chemical energy into electrical energy through the anode and cathode of the structure. Solid polymer fuel cell is a kind of battery which utilizes the characteristic that the electrolyte membrane only allows protons to pass through. Each battery cell consists of an anode, a cathode and an electrolyte membrane sandwiched between the electrodes. In order to obtain higher power output , usually a plurality of fuel cell cells are stacked. The electrolyte membrane in solid polymer fuel cells is a polymer that can be manufactured relatively easily and can operate at low temperatures. At the same time, the efficiency of energy conversion is higher...
