Combined accumulator and demineralizer functionality for a fuel cell

摘要

A fuel cell power plant assembly includes an accumulator having a housing. In one example, at least one demineralizer portion is positioned to interact with fluid within the accumulator housing. This allows for warm fluid within the accumulator housing to provide heat to the demineralizer portion. In one example, the demineralizer portion is within the housing. Another example includes a separator supported within the housing of the accumulator. A disclosed example includes a conical shaped baffle as the separator. The separator separates liquid from gas and facilitates distributing fluid flow within the accumulator housing to provide increased heat exchange with the demineralizer portion within the housing.
