The invention relates to the technical field of fuel cells, in particular to a fuel cell multi-module composite power supply power control method and system. The scheme comprises the following steps: setting a fuel cell sensing information base and corresponding key constraint parameters on line; according to a control parameter of the key constraint parameter before instability, determining a mandatory constraint and a conditional constraint; forming a standard constraint set and a non-standard constraint set; performing self-adaptive control in real time according to the control target of the current composite power supply in combination with the standard constraint set and the non-standard constraint set; according to the range of the standard constraint set, controlling the operation constraint range of each control quantity in real time; and when the non-standard rate of the control target reaches 5% and lasts for more than 5 minutes, automatically re-updating the standard constraint set and the non-standard constraint set to carry out adaptive control. According to the scheme, multi-module compound control is carried out by extracting various information amounts such as the electric pile temperature, the air flow and the air pressure on line, and optimal energy and stable control are achieved.
