Definitions

  • the invention relates to closed loop cooling of a fuel cell system, and in particular to addition and removal of water within a closed loop cooling circuit in relation to water ejected from a fuel cell stack.
  • Water is integral to the operation of a fuel cell system, for example in the form of the system described herein comprising a fuel cell stack based around a proton exchange membrane (PEM).
  • PEM proton exchange membrane
  • Excess water needs to be removed from the fuel cell stack to avoid flooding and causing a consequent deterioration in performance.
  • An amount of water needs to be present in at least the cathode flow path to maintain hydration of the PEM, so as to achieve optimum performance of the fuel cell.
  • Managing this water by deliberate injection and removal, can also provide a useful mechanism for removing excess heat from the fuel cell stack.
  • water can be employed deliberately in such fuel cell systems through injection, typically into the cathode flow path of the stack.
  • Such water injection fuel cell systems have potential advantages of reduced size and complexity, as compared with other types of fuel cell systems employing separate cooling channels.
  • Water may be injected directly into the cathode flow path through water distribution manifolds, as for example described in GB2409763.
  • the liquid water content of the cathode exit stream is usually insufficient for the water injection requirements of the fuel cell stack, because the water content of the exhaust is in the form largely of water vapour.
  • the temperature of the exhaust stream is therefore preferably reduced (e.g. using a heat exchanger) so as to reduce the dew point and condense at least part of the vapour to liquid water.
  • a method of separating the liquid water from the stream may also be used (e.g. a cyclonic separator) in order to ensure that the majority of the liquid water available in the stream is captured. Given the relatively low flow rate of the anode exit stream, it is usual to only recover the liquid water content (e.g. via an inline catch pot) as the benefit of additional water available due to reducing the dew point, e.g. by use of a further heat exchanger, is outweighed by the increased system complexity required.
  • the conductivity of the water introduced into a water injected fuel cell stack must be maintained at a sufficiently low level to avoid corrosion effects.
  • the liquid water leaving the fuel cell stack can contain fluoride and/or corrosion products (e.g. Fe etc.) which increase the conductivity of the water due to an increase in the ions from the total dissolved solids.
  • the conductivity of the water may increase due to any galvanic corrosion reactions that occur as a result of electrical potential difference between components. This can be minimised by careful selection of materials and the overall system design.
  • a method of operating a fuel cell system comprising a fuel cell stack and a closed loop water cooling circuit for direct injection of cooling water into the stack, the method comprising:
  • the coolant water in the fuel cell system can be maintained at a desired level of purity dependent on how the fuel cell is operating.
  • the operational parameter is optionally an electric current drawn from the fuel cell stack over the time period.
  • the proportion of the total amount of water removed from the closed loop cooling circuit may be in proportion with the current drawn over the time period.
  • the amount of water removed and added is then dependent on how hard the fuel cell is working, i.e. how much current is being supplied, which is in direct relation with the amount of fuel used.
  • the operational parameter may alternatively be the electrical conductivity, pH or total dissolved solids in the water within the closed loop cooling circuit.
  • the proportion of the total amount of water removed from the closed loop cooling circuit may be a function of a difference between a predetermined set point and the operational parameter.
  • the amount of water can be determined by controlling an outlet temperature of a heat exchanger in fluid communication with a cathode exhaust line of the fuel cell stack, for example by directing water removed from the closed loop cooling circuit on to an external surface of the heat exchanger.
  • a proportion of water which may be in the form of vapour
  • additional cooling to convert water vapour into liquid water is only required when more coolant is needed, and when this is not required the excess water, along with much of the heat, can be expelled as vapour.
  • the amount of water removed from the closed loop cooling circuit may be determined by controlling operation of a pump in fluid communication with the closed loop cooling circuit.
  • the pump may be operated intermittently with a duty cycle proportional to the amount of water to be removed from the cooling circuit. By only operating the pump when needed, the parasitic loads on the fuel cell can be reduced.
  • the amount of water to be removed may be calculated according to the relationship
  • W r is the amount of water to be removed from the cooling circuit
  • I is the current drawn from the fuel cell stack having n cells
  • F is the Faraday constant
  • ⁇ is a predetermined constant.
  • the constant ⁇ is preferably approximately 0.1.
  • a fuel cell system comprising a fuel cell stack, a closed loop water cooling circuit for direct injection of cooling water into the stack and a computerised controller, the controller being configured to automatically:
  • FIG. 1 shows a schematic representation of a fuel cell system for use in accordance with the invention.
  • the fuel cell system 100 comprises at least one fuel cell stack 110 and various connected components for the removal of water such as a heat exchanger 120 and cyclonic water separators 130 a , 130 b on the anode and cathode exit lines 140 , 150 respectively. These components enable liquid water to be recovered from the exit streams.
  • the fluid stream passing through the anode exit line 140 comprises water saturated hydrogen gas and liquid water from the anode volume in the stack 110
  • the fluid stream passing through the cathode exit line 150 comprises water saturated air and liquid water from the cathode volume in the stack 110 .
  • the cathode exit stream passes into the heat exchanger 120 , which is designed to cool the cathode exit stream sufficiently to allow liquid water to be extracted.
  • the extracted liquid water can then be recirculated into the closed loop cooling circuit.
  • the fuel cell system is configured to capture a proportion of the water discharged into the cathode exhaust line 150 of the fuel cell stack 110 and recycle that proportion for cooling and hydration of the membranes in the fuel cell stack.
  • the proportion is controlled as a fraction of an operational parameter of the fuel cell stack, as further detailed below.
  • a closed loop cooling circuit in the fuel cell system shown in FIG. 1 can be defined by the fuel cell stack 110 , the cathode exit line 150 , the heat exchanger 120 , the water separator 130 b , a cathode water return line 151 leading to a water storage vessel 160 and a water injection line 152 leading back to the fuel cell stack 110 .
  • the water injection line 152 preferably leads to the cathode volumes within the stack, where direct cooling can more effectively be achieved.
  • the closed loop circuit may also include the anode exit line 140 , water separator 130 a and anode water return line 141 , also leading to the water storage vessel 160 .
  • Pumps 180 a , 180 b , 180 c may be included in the cathode water return line 151 , anode water return line 141 and the water removal line 170 respectively, to aid the transport of water around and out of the cooling circuit.
  • a further pump (not shown) is preferably included within the water storage vessel 160 for pumping coolant water through the water injection line 152 into the fuel cell 110 .
  • the water storage vessel 160 preferably comprises a level sensor 165 to determine the level of water 166 within the vessel 160 .
  • the water in the closed loop cooling circuit is controlled according to the cooling and humidification requirements of the fuel cell stack 110 , with this typically being calculated in basic form as a function of the fuel cell stack 110 operating current. Excess water from the cooling circuit can be removed from the system through the water removal line by means of the pump 180 c.
  • An air compressor 111 is arranged to force air into the cathode volume of the fuel cell stack 110 via a cathode air inlet 112 .
  • Fuel in the form of hydrogen gas, enters the anode volume of the fuel cell stack 110 via an anode inlet fine 113 .
  • the exit temperature of the stream leaving the heat exchanger exit port 125 is controlled such that sufficient liquid water is recovered to allow a suitable level 166 within the water storage vessel 160 to be maintained.
  • a setpoint of 85% full is chosen for the level 166 in the water storage vessel 160 , with the remaining 15% used as a buffer to allow for hysteresis due to the thermal inertia of the heat exchanger 120 .
  • An amount of liquid water is therefore allowed to flow through the cathode water return line 151 into the water storage vessel, according to the chosen setpoint.
  • Control of the system 100 is preferably set such that the level 166 of water within the water storage vessel 160 is maintained irrespective of the water leaving the vessel through the water removal line 170 .
  • the thermal hysteresis as the heat exchanger cooling is reduced may be such that additional water will need be removed from the water storage vessel 160 .
  • the thermal characteristics of the heat exchanger 120 are known (either via calculation or empirical methods), the amount of water removed from the water storage vessel 160 due to the overflow would also be known. Hence, it is possible to control the heat exchanger cooling such that a required amount of water is removed from the water storage vessel 160 .
  • a more accurate means of removing liquid water from the storage vessel is by use of a pump 180 c .
  • a pump may be either continually variable or of fixed operation. If the pump 180 c is continually variable according to a setpoint, the flow rate as a function of setpoint is obtained with the pump 180 c providing liquid to the atmosphere via the water removal line 170 . Thus, this data can be used to achieve a required flow rate by adjusting the setpoint accordingly.
  • the flow rate of the pump is calibrated with it pumping water to atmosphere. This flow rate is thus the maximum that can be achieved. If a flow rate below this maximum is required, the pump 180 c can be switched on and off, according to a suitable duty cycle.
  • the pump 180 c will operate for a percentage of this time according to the ratio of the required flow rate to the maximum. For example, if the pump 180 c is calibrated to deliver 100 ml/min, and a flow rate of 25 ml/min is required, then the pump is switched on for 15 seconds, and then off for 45 seconds, with this cycle repeated every 60 seconds. As well as increased accuracy, the use of a pump 180 c to remove the water has an additional benefit when the fuel cell system 100 comprises an air cooled heat exchanger 120 . In this situation, the excess water from the water removal line 170 may be sprayed onto the heat exchanger 120 to aid cooling, and thus allow the heat exchanger 120 to be smaller than would otherwise be required to generate the liquid water for replenishing the cooling circuit.
  • the amount of liquid water that should be added and removed from the closed loop system can be calculated as a function of the total amount of water generated due to the electrochemical reaction in the fuel cell stack 110 . This can be calculated as follows.
  • W p In 2 ⁇ F ⁇ ⁇ moles ⁇ ⁇ s - 1 ,
  • I is the fuel cell stack current (in Amps)
  • n is the number of cells in the fuel cell stack 110
  • F is the Faraday constant (approximately 96.5 ⁇ 10 3 Coulombs per mole).
  • the relative molecular mass of water is 18.0 g mole ⁇ 1
  • the density of water is 0.998 g cm ⁇ 3 at 20° C., hence:
  • the amount of liquid water to be removed from the cooling circuit, W r can be expressed as,
  • ⁇ is the proportion of liquid water to be removed, as compared to the total amount of water generated by the fuel cell stack 110 .
  • a preferred value for ⁇ is 0.1 as this provides an acceptable balance between heat exchanger size and dilution of the liquid water within the closed loop, although this value can be varied according to requirements.
  • the amount of water to be removed for any given size of fuel cell can be described as being directly proportional to the fuel cell stack current.
  • An alternative to the above approach is to measure the conductivity or other operational parameter (e.g. pH, total dissolved solids, etc.) of the liquid water entering the fuel cell stack 110 .
  • the amount of water to be removed from the system, and therefore the amount of liquid water to be drawn from the cathode exit line 150 can be derived as a function of a calculated error between a setpoint of conductivity or other parameter and the measured value.
  • a standard control loop e.g. proportional, integral, derivative: PID
  • PID proportional, integral, derivative
  • the fuel cell system preferably comprises a suitable computerised controller connected to the various relevant components of the fuel cell system 100 .
  • the controller is configured to automatically determine the amount of water to be removed from the closed loop cooling circuit as a function of a particular operational parameter.
  • the controller can be configured to monitor the current drawn from the stack 110 , determine from this measurement the amount of water to be removed from the closed loop cooling circuit, and adjust operation of the pumps 180 a , 180 b , 180 c accordingly.
  • the controller may be configured to control operation of the water separators 130 a , 130 b , and the amount of water (if any) to be sprayed on to the heat exchanger 120 for additional cooling.
  • the controller may be configured to monitor operational parameters such as water conductivity, pH or dissolved solids, and adjust the amount of liquid water removed from the cooling circuit accordingly. For example, if the conductivity of the liquid water within the cooling circuit rises, the controller may be configured to increase the amount of liquid water removed from and added to the cooling circuit, so as to dilute the cooling water with fresh water generated in the fuel cell stack 110 , and thereby reduce the conductivity of water in the cooling circuit.
