Embodiment Construction

[0020] Below the attachment in the embodiments of the invention will be clearly and fully described in the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technical personnel in the art under the premise of not creating creative labor belong to the protection of the present invention.

[0021] The air -cooled fuel cell pile 2 and liquid cold fuel cell pile 1 are two different fuel cell systems, which are generally used in different fields. The electric heap of liquid cooling fuel cells must reach extremely high power density under the blessing of various peripheral equipment, pursuing small volume and high power. Electric Cold Fuel Battery Pack 2 is to abandon the peripheral equipment, streamline the system as a whole, and pursue the performance when the environm...

Abstract

The invention involves the field of fuel cell technology, which specifically involves a combination system that specifically involves an air -cooled fuel cell and liquid cooling fuel cell, including the air -cooled fuel cell electric heap and liquid cold fuel cell pile.As a source of hydrogen supply for the air -cooled fuel cell pile, the air -cooled fuel cell pile is entered so that the discharge of hydrogen is discharged after the air -cooled fuel cell pile.The combined system of the air -cooled fuel cell and liquid cooling fuel cell has eliminated the hydrogen circulation pump and attached pipeline, gas -water separators and control components, eliminating the control conversion of hydrogen plus humidifiers and two -stage voltage of air -cooled fuel cells.The risk of hydrogen leakage simplifies the system structure, improves system reliability, and increases the power density of the system, and solves the problem of two -stage voltage output problems.

Description

Technical field [0001] The invention involves the field of fuel cell technology, which specifically involves a combination system for air -cooled fuel cells and liquid cooling fuel cells. Background technique [0002] At present, for a separate air -cooled fuel cell system or liquid cooling fuel cell system, the hydrogen circulating pump is mainly used to use hydrogen circulation to increase the use of hydrogen circulation. However, the weight of the hydrogen circulation pump is large. Due to the existence of the hydrogen circulating pump, the volume of the fuel cell system will be greatly increased, and additional power consumption and the risk of leakage are generated. Invention content [0003] In order to overcome the deficiencies of existing technology, the present invention provides a combination system for air -cooled fuel cells and liquid cooling fuel cells, eliminating the hydrogen circulation pump, simplifying the system structure and attachment of pipelines, gas and w...
