The invention relates to a modular fuel cell system architecture and a control system to distribute power to modules. Systems and methods for modularizing a system are provided. Parallel power systems with electrically isolated high voltage systems facilitate modularization. A control system is provided that optimizes the distribution of power demand and/or torque requests in order to maintain the efficiency, durability, drivability and/or safety of the system within optimal ranges. In some cases, the distribution of power is non-uniform in order to extend battery life, while in other cases, the power draw across the battery system remains equal and constant in order to appropriately manage the state of charge of the parallel power system. In other cases, the selected power distribution maintains the power demand and/or torque request between minimum and maximum levels/capacities, and the power distribution avoids on/off of a single power system. 本公开涉及模块化燃料电池系统架构和将电力分配到模块的控制系统。提供了用于使系统模块化的系统和方法。具有电隔离的高压系统的并联电
