₹70 Photocatalytic Fuel Cell from BITS Pilani-Hyd Powers IoT Innovation
Photocatalytic fuel cell technology has taken a major step forward as researchers at BITS Pilani–Hyderabad developed a low-cost prototype priced at just ₹70. The team said the photocatalytic fuel cell can power small IoT devices without needing external electricity, making it ideal for sensors and remote monitoring systems.
Researchers explained that the device uses light-activated materials to generate energy while simultaneously cleaning pollutants present in water. This dual function reduces both power costs and environmental impact. The team added that such a system can support IoT deployment in rural, industrial, and agricultural settings where conventional power sources are unreliable.
According to the institute, the design is simple, affordable, and easy to scale for mass production. Early tests showed that the fuel cell can operate efficiently under indoor and outdoor lighting conditions. Faculty leaders noted that this innovation could help India strengthen its position in sustainable tech and low-cost electronics.
Students involved in the project said the next phase includes improving durability and integrating the cell with wireless modules. The institute plans to collaborate with industry partners to explore commercial applications. Experts believe that such cost-effective energy solutions will accelerate the growth of self-powered smart devices across the country.
