Fuel cell runner structure, flow field plate and fuel cell

Abstract

The invention provides a fuel cell flow channel structure, a flow field plate and a fuel cell, which are used for solving the problems of flow channel water accumulation and poor cell stability of thefuel cell in the prior art. The fuel cell flow channel structure comprises an upper triangular area and a lower triangular area; the upper triangular area is provided with plurality of horizontal flow channels, and in every two vertically adjacent horizontal flow channels, length of the upper horizontal flow channel is larger than that of the lower horizontal flow channel; the lower triangular area is provided with a plurality of vertical flow channels; the vertical flow channels and the horizontal flow channels correspond to one another to form L-shaped flow channels, and the longer verticalflow channels correspond to the longer horizontal flow channels; each horizontal flow channel and one end far away from the lower triangular area are respectively communicated with an inlet pipeline;the ends, away from the upper triangular area, of the vertical flow channels communicate with an outlet pipeline; the fuel cell flow channel structure comprises an oblique angle flow channel which islocated between the upper triangular area and the lower triangular area, and the horizontal flow channels and the vertical flow channels are communicated with the oblique angle flow channel.

Description

technical field [0001] The invention relates to the field of new energy batteries, in particular to a fuel cell flow channel structure, a flow field plate and a fuel cell. Background technique [0002] Proton exchange membrane fuel cell is considered as an ideal power source suitable for human development and environmental requirements due to its advantages of high efficiency, high energy and low pollution. The bipolar plate (flow field plate) is an important part of the proton exchange membrane fuel electromagnetic, and its mass accounts for more than 60% of the battery stack. The flow channel design on the flow field plate has a great impact on battery performance, operating efficiency, and manufacturing cost. [0003] The flow channels of the existing flow field plates include serpentine flow channels, parallel flow channels, multi-channel serpentine flow channels, spiral flow channels, metal mesh flow channels, foam material flow channels, etc. The problems existing in ...
