Improved fluid passages for power generation equipment

A cooling apparatus (100) for fuel cell components is provided wherein the cooling apparatus comprises a base plate (110) having a first end (112) and a second end (114) and a first side plate (120) coupled to the first end (112) and a second side plate (125) coupled to the second end (114). A plurality of bottom ribs (160) are coupled to the base plate (110) and a plurality of upper ribs (150) are coupled to the bottom ribs (160). In addition, a top channel (130) and a bottom channel (140) are formed between each of the plurality of upper ribs (150) and each of the plurality of bottom ribs (160), respectively, wherein the top channel (130) and the bottom channel (140) are disposed to allow a flow of a fluid (210) therethrough and disposed to allow a portion of the fluid (210) to alternate between the top channel (130) and the bottom channel (140) at a flow redirection area (170) so as to enhance the heat transfer rate between the fluid (210) and the fuel cell components.
