AI Technical Summary
In existing hydrogen fuel cells, the carrier effect between carbon support and metal particles is limited during the reverse polarization process, which means that catalyst deactivation and carbon corrosion cannot be completely avoided in long-term applications, affecting the durability and safety of the battery.
Using titanium dioxide material loaded with noble metals as a catalyst support, an anti-reverse polarization catalyst was prepared by liquid nitrogen freeze-drying and high-temperature heat treatment. The content of metal elements and the distribution of components were controlled to enhance the stability and catalytic ability of the catalyst.
It effectively suppresses reverse polarity, extends battery life, improves catalyst stability and corrosion resistance, and maintains high catalytic activity.
