Abstract: A managing method of the start-up phase of at least one micro fuel cell (11) to be connected to a load (12) is described as comprising the steps of:
- measuring a micro fuel cell voltage value (V FC ) across the micro fuel cell (11) activated by means of a fuel injection;
- comparing the micro fuel cell voltage value (V FC ) with a first predetermined threshold voltage value (V TH ); and
- establishing an operation mode of the micro fuel cell (11) according to the following conditions:
- as long as the micro fuel cell voltage value (V FC ) is lower than the first threshold voltage value (V TH ), the micro fuel cell (11) operates in a first open circuit state (S1), during which it is not connected to the load (12);
- when the micro fuel cell voltage value (V FC ) overcomes the first threshold voltage value (V TH ), the micro fuel cell (11) passes to a second pre-ignition state (S2), during which it supplies a current value (I FC ) corresponding to the first threshold voltage value (V TH ), according to a static voltage-current or V-I characteristic of the micro fuel cell (11).
A managing circuit (10) of the start-up phase of at least one micro fuel cell (11) to be connected to a load (12) is also described.
