A fuel cell assembly (20) includes an electrochemically active portion (40) that operates at an average operating temperature within a temperature range that is selected based upon an expected life cycle of the fuel cell assembly (20). In a disclosed example, the average operating temperature range for the electrochemically active portion is between about 340°F (171°C) and about 360°F (182°C). Maximum and minimum operating temperatures of the electrochemically active portion may be outside of the average operating temperature range. In one example, the electrochemically active portion is maintained at a temperature of at least 300°F (149°C) and less than 400°F (204°C). |
