Abstract

The invention relates to a parallel fuel cell electric power system. The parallel fuel cell electric power system comprises multiple groups of fuel cell electric power modules and a direct current bus, wherein each fuel cell electric power module includes a fuel cell stack, a current switch and a countercurrent protection component; the direct current bus is in an electric connection with output terminals of the fuel cell electric power modules and makes all the fuel cell electric power modules in parallel to effectively combine fuel cell stacks with a fixed power capacity into fuel cell stack groups so as to provide voltages with different power output for load usage.

Description

technical field [0001] The invention relates to a parallel fuel cell power system, in particular to a parallel fuel cell power system in which fixed power fuel cell stacks are combined into different power outputs. Background technique [0002] Fuel Cell (Fuel Cell) is a pollution-free green power generation technology, and this power generation technology is a device that uses electrochemical principles to directly convert the chemical energy in the fuel into electrical energy and release heat energy. [0003] A fuel cell is an electrochemical device that produces electricity and water by electrochemically reacting an oxidant with a fuel in the form of a proton source. Of these, the most common fuel is hydrogen, while the most common oxidizer is oxygen and is typically delivered as a gas stream. In practice, the fuel is delivered to the anode region of the fuel cell, and the oxidant is delivered to the cathode region of the fuel cell, and the anode region is separated from...
