摘要： A fuel cell stack includes power generation cells, which are stacked in a vertical direction. Each power generation cell is configured to generated power by using gas. Each power generation cell includes a first hole and a second hole. The first holes of the power generation cells form a gas manifold. The gas manifold extends in the vertical direction, and the gas flows through the gas manifold. The second holes of the power generation cells form a passage. The passage is adjacent to the gas manifold and extends in the vertical direction. The gas manifold and the passage are connected to each other at upper ends of the gas manifold and the passage.

摘要： Provided are flow batteries, comprising: a first reservoir containing a first electrolyte solution and one or more battery packs. A battery pack comprises a battery stack, an enclosure enclosing the battery stack, a first supply flow path, and a first return flow path. The first supply flow path comprises a substantially U-shaped bend such that a first portion of the first supply flow path and a second portion of the first supply flow path are positioned substantially parallel to each other and within the enclosure. The first return flow path comprises a substantially U-shaped bend such that a first portion of the first return flow path and a second portion of the first return flow path are positioned substantially parallel to each other and within the enclosure. These flow batteries are useful to mitigate inter-stack shunt currents.

摘要： The present disclosure relates to mode selective electrode assembly. Further, the present disclosure relates to a unitized regenerative fuel cell comprising a mode selective electrode assembly which operates in dual mode that is electrolysis cell mode and fuel cell mode. The unitized regenerative fuel cell further comprises of at least two gas storage tanks with pressure sensors for storing hydrogen gas and oxygen gas, a water storage tank with pressure sensor, an external energy source, and a power reservoir for storing energy. The mode selective electrode assembly comprises a mode switching system that automatically changes the electrode assembly from an electrolysis cell mode to a fuel cell mode and/or from a fuel cell mode to an electrolysis cell mode, by changing the reactive polymeric layers of the electrodes. The present disclosure also relates to a method for operating a unitized regenerative fuel cell.
