As the world is talking about net zero and making a transition from fossil fuels to renewable sources such as hydrogen fuel cells, there exists a significant opportunity to develop remarkable new technologies in the generation of electricity. Utilizing hydrogen to power fuel cells that generate electricity is a sustainable alternative to fossil fuels since the byproduct is water. However, there are certain challenges, such as temperature maintenance for hydrogen filling stations.
