AI Technical Summary

Technical Problem

The existing fuel cell humidification device requires regular water addition, which increases the difficulty of maintenance of fuel cells and is not very humidified, affecting the power generation performance of fuel cells.

Method used

A fuel cell humidifier is designed, including a housing, a hydrogen diffusion layer, anode layer, a proton exchange membrane, a cathode layer and an oxygen diffusion layer. The humidifier atomizes the generated water through an ultrasonic atomizer, and uses a humidification tube and a delivery pump to send humidification air to the side of the hydrogen guide plate to achieve synchronous humidification treatment.

Benefits of technology

By collecting and utilizing the generated water, the water loss is reduced, the humidity efficiency is improved, the fuel cell maintenance difficulty is reduced, and the delivery fan for humidification is saved, simplifying the structure.
