Abstract
A fuel cell temperature control assembly comprising inner and outer valve members, the outer valve member having first and second ports adapted to receive fresh supply gas and heated flue gas, respectively, and a third port displaced from the first and second ports and adapted to be connected to the input port of a fuel cell, the inner valve member having input and output coupling ports and sealing means for ensuring coupling of the first and second ports of the outer valve member to the third port of the outer valve member only through the input and output coupling ports of the inner valve member.
Claims15
An assembly for use in controlling the temperature of a fuel cell having input and output ports for receiving supply gas and discharging exhaust gas, said assembly comprising:
- an outer valve member including first, second, and third ports, said first and second ports being spaced and adapted to receive supply gas at first and second temperatures, respectively, said first temperature being higher than said second temperature, said third port being displaced from said first and second ports and being adapted to connect to said input port of said fuel cell;
- an inner valve cylinder having an input coupling port and an output coupling port, said inner valve member being movably mounted in said outer valve member such that said input coupling port in the position of said first and second ports overlaps said first and second ports, respectively, and such that said output coupling port communicates with said third port;
- and means for sealing said first and second ports from said third port such that coupling between said first and second ports and said third port occurs only through said input and output coupling ports.
