A traveling-wave flow field is proposed and investigated for the performance improvement effect of proton exchange membrane fuel cell (PEMFC). This study analyzes influence multiple structural parameters length, wave height, number, spacing on law, mass transfer characteristics field, PEMFC performance, obtains weight coefficient each parameter through Grey-relational theory. Results show that has excellent oxygen transport drainage functions, its corresponding functional structures are...
In order to achieve “Strong mass transfer” and “Low pressure drop” in the flow field, this paper adopts “Bionic” design idea carry out three-dimensional channel performance test of bionic peregrine falcon structure, main research contents are as follows: firstly, abdominal structure is extracted, fuel cell designed, single-channel model established simulation. At same time, with straight channel, trapezoidal block sinusoidal compared. The results show that maintains minimum drop peak power...
In existing fuel cell flow field design, porous fields have shown to excellent self-humidifying capability due its highly controllable pore space, capillary pumping ability, and certain structural flexibility. However, the uniformly distributed structure is difficult adapt complex water-gas distribution inside cell. Therefore, this paper designs an optimized based on pre-developed fiber field. Experimental results show that, compared with original cell, peak power density of increased by...
