The recently launched India’s first indigenously developed hydrogen fuel cell ferry marked a milestone in harnessing clean energy for sustainable transportation. As nations race to tap hydrogen’s potential, an appraisal of fuel cell tech, policy initiatives and challenges can shape India’s zero emission mobility roadmap.
Hydrogen Fuel Cells
Working Mechanism
- Hydrogen fuel cells generate power electrochemically by combining hydrogen and oxygen atoms without any direct combustion
- They have two electrodes—anode and cathode separated by an electrolyte medium
- Hydrogen fed at anode splits into protons and electrons which recombine at cathode with oxygen to produce electricity
Advantages Over Batteries
- High energy density enables longer operating range
- Rapid refuelling compared to recharging, operational in minutes
- Modular stacking allows power output customization
Limitations
- High costs due to noble metal catalysts like platinum
- Production and distribution of hydrogen as fuel poses infra challenges
- Susceptible to poisoning by impurities like carbon monoxide
