Abstract
The invention provides a fuel cell stack and a fuel cell stack system therewith. The fuel cell stack includes a first insulating plate, a first current collecting plate, multiple cells, a second current collecting plate and a second insulating plate which are sequentially disposed, wherein the first current collecting plate is assembled on the first insulating plate, the second current collectingplate is assembled on the second insulating plate, the first current collecting plate and / or the second current collecting plate includes multiple sub current collecting plates arranged at intervals,and each sub current collecting plate is capable of collecting the current of each cell and a corresponding region of the sub current collecting plate. The fuel cell stack is advantaged in that a problem that performance of the fuel cells in the prior art can only be determined by the voltage of the whole cell stack or by the voltage of each cell in the cell stack and a problem of specific performance distribution inside the stack cannot be mastered in the determination process are solved.
Description
technical field [0001] The present invention relates to the field of batteries, in particular, to a fuel cell stack and a fuel cell stack system having the same. Background technique [0002] In the prior art, a fuel cell is an environmentally friendly, high-efficiency, long-life power generation device. Taking the proton exchange membrane fuel cell (PEMFC) as an example, the fuel gas enters from the anode side, the hydrogen atoms lose electrons at the anode and become protons, the protons pass through the proton exchange membrane to the cathode, and the electrons also reach the cathode through the external circuit, at the cathode protons , electrons and oxygen combine to form water. The fuel cell converts chemical energy into electrical energy in a non-combustion manner, and its direct power generation efficiency can be as high as 45% because it is not limited by the Carnot cycle. With the battery stack as the core power generation device, the fuel cell system integrates ...
