    Abstract: An evaporative heat exchanger (10) is provided for the transfer of heat to a first fluid (30) from a second fluid (28) and a third fluid (22) to vaporize the first fluid (30). The heat exchanger (10) includes a core (40), a first flow path (60) in the core for the first fluid (30), a second flow path (66) in the core (40) for the second fluid (28), and a third flow path (68) in the core (40) for the third fluid (22). The core (40) includes a first section (42), a second section (44), and a third section (46), with the second section (44) connecting the first and third sections (42, 46). The first flow path (60) extends through all of the sections (42, 44, 46), the second flow path (66) extends through the first section (42), and the third flow path (68) extends through the third section (46).

    Abstract: A heat exchanger (50) is provided for transferring heat between first and second fluids (52) and (54) having a maximum operating mass flow rate through the heat exchanger (50) and mass flow rates that are substantially proportional to each other. The heat exchanger (50) provides essentially constant outlet temperatures for the first and second fluids (52,54) for all of the flow rates within the operating spectrum of the heat exchanger (50) without the use of an active control system. The heat exchanger (50) is of particular use in the fuel processing system (36) of proton exchange membrane type fuel cell systems.
