example 1

[0067] Example 1: Taking the first pilot valve plate 2 as 0° to 90° and the second pilot valve plate 3 as 0° to 90° as an example, there are 8100 arrangements and combinations of the first pilot valve plate 2 and the second pilot valve plate 3, specifically is {0°, 0°}, {0°, 1°}···{0°, 90°};

[0068] {1°, 0°}, {0°, 1°}···{0°, 90°};

[0069] ···

[0070] {90°, 0°}, {0°, 1°}···{0°, 90°}.

[0071] Then each humidity is corresponding to the combination of the opening degrees; and the opening combinations are entered into the controller 5 one by one according to the humidity range; since in the case of a given air flow, each opening combination represents a humidity in a high probability value. When encountering a humidity value and there are multiple corresponding opening combinations, the opening combination whose opening variation trend matches the adjacent humidity value should be selected.

[0072] In addition to the above-mentioned embodiments, the present invention als...

Abstract

The invention provides a humidifier for a fuel cell system and a debugging and working method of the humidifier. The humidifier is characterized in that a plurality of humidifying membrane assemblies are arranged in the humidifier; the humidifier is provided with a dry air flow channel and a wet air flow channel; the dry gas flow channel and the wet gas flow channel coincide at the humidifying film assembly; a humidity sensor is arranged at the outlet end of the dry gas flow channel; the first guide valve plate is arranged at the inlet end of the dry gas flow channel or the wet gas flow channel; the opening degree of the first guide valve plate is adjusted through the first actuator, the flowing path of the airflow is changed, the contact space of the airflow and the humidification membrane assembly is increased or decreased, and wet airflow and dry airflow conduct moisture exchange through the humidification membrane assembly which is in contact with the first guide valve plate. The flowing path of the air flow can be changed through the arranged first guide valve plate, so that the dry air flow passes through the wetted humidifying film assembly as much as possible, and the humidity of the output dry air flow is finely adjusted under the condition of the same air inflow.

Description

technical field [0001] The invention relates to the technical field of a humidifier, in particular to the technical field of a humidifier used in a fuel cell system. Background technique [0002] A fuel cell is a power generation system that converts the chemical energy of fuel into electrical energy by chemically reacting with oxygen or other oxidizing agents. Hydrogen is typically the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are also sometimes used as fuels. [0003] A fuel cell system typically includes a cell stack that includes a plurality of individual fuel cells forming a power generating assembly, each having a cathode and an anode that allow electrical charge to move across the fuel cell. The fuel cell system also includes an air supply device that supplies air to a cathode of the fuel cell and a hydrogen gas supply device that supplies hydrogen to an anode of the fuel cell. Here, hot and humid air is exhausted from the cat...
