FUEL CELL GAS MANAGEMENT SYSTEM

摘要

A fuel cell gas management system (10) including a cathode humidification system (30) for transferring latent and sensible heat from an exhaust stream (16) to the cathode inlet stream (14) of the fuel cell (26); and anode humidity retention system (80) for maintaining the total enthalpy of the anode stream (20) exiting the fuel cell equal to the total enthalpy of the anode inlet stream (18); and a cooling water management system (130) having segregated deionized water and cooling water loops interconnected by means of a brazed plate heat exchanger.
