Hi,
I'm developing an application called Hybrid Solar-Fuel cell off grid kit.
I'll be using a solar cell to power a Hydogen Fuel cell which is then used to charge a 12 V rechargeable battery.
The No Load Voltage of the solar cell is approximately 3 Volts. During solar-powered electrolysis, you can typically expect to generate approximately 1.7 Volts.
The fuel cell has a No-Load Voltage of about 1.7 Volts and an Operating Voltage of about 0.9 V having a current in the range of 100 to 300 mA.
So i need to boost 0.9 V,300mA to charge a 12V rechargeable battery.
And its a standalone device having no auxillary supply. So the only supply is 0.9 V, 0.3A(300mA)
Please do suggest me a suitable converter.
