A fuel cell system suppresses the deterioration of an electrolyte membrane of a fuel cell. The fuel cell system comprises: a temperature rise speed calculation unit for calculating a target temperature rise speed of the fuel cell using a temperature of the fuel cell and a water content of the fuel cell; and a drive control unit for controlling a drive of the cooling water pump using the temperature rise speed of the fuel cell and the target temperature rise speed calculated by the temperature rise speed calculation unit. The drive control unit controls the drive of the cooling water pump such that a circulation amount of the cooling water is decreased when the temperature rise speed of the fuel cell is below the target temperature rise speed and controls the drive of the cooling water pump such that the circulation amount of the cooling water is increased when the temperature rise speed of the fuel cell is equal to or greater than the target temperature rise speed.

This fuel cell system is for suppressing a backflow of water from an exhaust pipe outlet that discharges a reactant-off gas, without decreasing the performance and fuel consumption of a fuel cell, the exhaust pipe being configured to switch between a main discharge pipe and a sub discharge pipe by a switching means to discharge the reactant-off gas. The sub discharge pipe includes a rising gradient portion formed to incline upwards above a gradient of the main discharge pipe and a falling gradient portion formed to incline downwards at the downstream of the rising gradient portion. The switching valve switches to allow the reactant-off gas to be discharged from the main discharge pipe if an amount of reactant-off gas to be discharged is equal to or above a threshold value of an amount of discharge, and allow the reactant-off gas to be discharged from the sub discharge pipe if the amount of reactant-off gas to be discharged is below the threshold value of the amount of discharge.

A fuel cell module has a hydrogen recirculation pump and a controller. The controller receives a signal indicating the response of the pump to changes in the density or humidity of gasses in the hydrogen recirculation loop. The controller is programmed to consider the signal in controlling one or more balance of plant elements that effect the removal of water from the stack. In a process for operating the fuel cell module, the signal is considered when controlling one or more balance of plant elements that effect the removal of water from the stack. For example, an increase in current drawn from a constant speed or voltage recirculation pump indicates an increase in humidity and suggests that water should be removed from the stack, for example by increasing a coolant temperature set point.

A water vapor transfer unit having fluid flow conduits which distribute wet or dry fluid throughout the water vapor transfer unit, which are created by forming apertures in each wet and dry plate so that when the plates are stacked, fluid flow inlet and outlet headers are integrated into the flow stack. These integrated headers negate the need for traditional wet and dry fluid inlet and outlet manifolds external to the water vapor transfer unit stack. Because the plates are stacked and sealed so that the fluid flows cannot co-mingle, the fluids are introduced directly into the stack, flow across the flow fields, and exit the stack without leakage or flow contamination. The integrated header design allows for sealing the stack on no more than a single plane defined by the stack or on no more than two parallel opposing planes and allows for accommodation of stack expansion and contraction. 1.

A fuel cell stack assembly is disclosed that includes a porous member disposed within a flow path for a reactant. A fluid collection member is provided within the flow path adjacent to and in fluid communication with the porous member. The porous member and the fluid collection member cooperate to collect liquid water from the reactant flowing in the flow path, wherein the collected liquid water may be drained from the fluid collection member. 1. A fluid regulation system for a fuel cell stack comprising:a porous element disposed in an inlet formed in a first end plate of the fuel cell stack, a peripheral edge of the porous element abutting a surface forming the inlet, wherein the porous element spans the inlet, the porous element effective to collect a liquid water from a reactant gas flowing therethrough; anda fluid collection member disposed in an inlet conduit in fluid communication with the inlet, the fluid collection member in fluid communication with the porous element.2. The system according to claim 1 , wherein the porous element is formed from a hydrophilic material.3. The system according to claim 1 , further comprising a fluid conduit in fluid communication with the fluid collection member to provide a flow path to drain the liquid water from the fluid collection member.4. The system according to claim 3 , including a flow restrictor disposed in the fluid conduit to control a flow of the reactant gas therethrough.5. The system according to claim 4 , wherein the flow restrictor is one of a nozzle claim 4 , a wicking material claim 4 , and a hydrophilic porous element.6. The system according to claim 3 , wherein the porous element is formed from one of a hydrophilic material and a hydrophobic material.7. The system according to claim 1 , wherein the porous element collects a liquid water entrained in the reactant gas flowing through the porous element.8. The system according to claim 7 , wherein the liquid water collected is received in the fluid ...
