Hydrogen & Fuel Cells

The video explores the potential of using hydrogen, oxygen, and sunlight to power future vehicles. It explains how photosynthesis inspires the process of splitting water into hydrogen and oxygen, with hydrogen stored as fuel. Fuel cells efficiently convert chemical energy to electricity, but challenges include sourcing and storing hydrogen. Current methods derive hydrogen from methane, contributing to greenhouse gases. Research focuses on hydrides for safer storage. Despite these efforts, battery-powered vehicles may be more energy-efficient. The video concludes that while fuel cells are promising, batteries might dominate future vehicle power.

What alternative energy source is suggested for powering vehicles instead of hydrogen fuel cells?

How does a fuel cell generate electricity from hydrogen and oxygen?
