boost converter for ultra low power application

I want to design a dc-dc boost converter and manage power (MPPT) for an ultra-low power fuel which contains input voltage < 1v1 V and input current < 500 uauA. if I choose simple boost converter, I will have problem with inductor design because low input current (about 500ua500 uA) will cause extremely high inductor. here

Here is the formula for calculating inductor for simple boost converter [L= (VinD)/(fs0.3*iL)] so 

I need to choose high freq and high L that means an inductor with more than 10mH10 mH inductance and work in 5MHZ5 MHz freq. (we don't have inductance in this spec) what should I do for power managing of this ultra-low fuel?
