Abstract

The invention provides a fuel cell system and a centrifugal water separator for the fuel cell system. The fuel cell system includes a fuel cell stack in fluid communication with a separator. The separator has a first portion and a second portion forming a chamber. The first portion has a continuous inner wall and an end wall, with an inlet conduit connected to the inner wall and a liquid drain connected to the end wall. The second portion has an end wall and an outlet conduit extending into the chamber to form a channel with the inner wall of the first portion. A fuel cell separator includes a first end and a second end connected by a side wall to define a separation chamber. An inlet conduit is tangentially connected to the wall. An outlet conduit is connected to the first end and extending into the chamber to form a channel with the wall. A liquid drain is connected to the second end.

Description

technical field [0001] Embodiments relate to an apparatus for removing water from a fuel cell system. Background technique [0002] During fuel cell operation, by-products such as product water and nitrogen, as well as undepleted hydrogen, may form on the anode side of the fuel cell stack. In some known systems, the accumulation of product water, as well as the accumulation of nitrogen, is controlled in an attempt to avoid degrading the performance of the fuel cell and / or avoiding shutdown of the fuel cell system. One known method is to release water and nitrogen through channels downstream of the fuel cell stack. The by-products can be recycled so that undepleted hydrogen is returned to the anode side of the fuel cell stack. Additionally, recirculation can be used to humidify the anode side to facilitate efficient chemical conversion and extend the life of the battery membrane. However, liquid water, such as droplets, may need to be removed from the recirculation flow to...
