Abstract
In order to adapt the regulation of the residual gas ejection via disposal valves (14, 15) to the boundary conditions within a closed air-independent system in a fuel cell system, in which the reactants hydrogen (H2) and oxygen (O2) circulate in separately regulated gas circuits (8, 9), sensors (17, 18) for measuring the concentrations (c
Description
Fuel cell system, and method for operating it in an airindependent system
The invention relates to a fuel cell system for operation in an air-independent installation, with a number of fuel cells which, for supply with the reactants hydrogen and oxygen, are connected into two separate gas circuits of the two reactants, wherein the reactants can be introduced into the relevant gas circuit via a supply valve and discharged therefrom via a discharge valve into the air-independent installation in each case, and with a regulation device for regulating the introduction and discharge of the reactants and also their circulation in the gas circuits as a function of the measured gas concentrations of the reactants in the gas circuits.
The invention further relates to a corresponding method for the operation of a fuel cell system in an air-independent installation .
A system of this type is known from WO2015024785 (Al).
Fuel cells enable an emission-free and low-noise generation of electrical energy, for which reason they are increasingly being used in floating or submersible devices in order to generate the electric energy required there. Examples of floating or submersible devices of this kind are surface vessels, subsurface vessels (submarines) or offshore platforms. Thus, for example, many modern submarines have an air-independent drive, in which fuel cells, together with a battery, supply an electrical propulsion drive of the submarine as well as all further electrical consumers with
PCT/EP2017/057429 / 2016P06345WO electrical energy during submerged travel. During snorkel travel or in the surfaced state, on the other hand, the energy supply takes place by way of a diesel generator.
In this context, the fuel cells are usually operated with technically pure hydrogen and oxygen as reactants, which react in the fuel cells to form product water. In order to minimize the quantity of non-combusted residual gases to be discharged and to make optimal use of the reactants, the two reactants are fed to the fuel cells in a circulating operation in each case in the fuel cell system known from the aforementioned WO2015024785 (Al). Since the reactants contain a low proportion of inert gases from the manufacturing process, depending on their level of purity, their purity is progressively reduced due to the circulating operation, with the result that they need to be removed from the circuits and replaced with fresh reactants when they have a corresponding impurity. In the known fuel cell system, the discharge of reactants out from the gas circuits and the introduction of fresh reactants and their circulation in the gas circuits is regulated as a function of measured concentrations of the reactants in the gas circuits. In this context, in each of the two gas circuits, as the concentration of the respective reactant drops, firstly the circulation rate is increased; if a minimum concentration of the respective reactant is reached, then some of the reactant is discharged from the gas circuit as residual gas and replaced with new reactant.
While the oxygen-containing residual gas as a rule can be mixed with the ambient air without issues, there is an inherent fire risk in the case of the hydrogen-containing residual gas. As described in DE102006026539 (Al), in known fuel cell systems in air-independent installations the
2017242515 12 Jun2019 hydrogen-containing residual gas is therefore guided into a safe region of the installation with the aid of a line, and only there is it released into the ambient air. The safe region involves a region at the overhead level of the operating personnel of the fuel cell system, for example.
Since a combustible gas mixture is always present in the vicinity of the residual gas outlet, however, it is known to circulate the ambient air through a catalytic reactor with the aid of a fan, in which catalytic reactor the hydrogen is converted into water along with the oxygen, so that ignitable mixtures in the ambient air are prevented. In order to enable a discharge of the hydrogen-containing residual gas without the risk of fire, even without the use of a catalytic reactor, in the cited document DEI02006026539 (Al) it is proposed to mix the hydrogencontaining residual gas with the oxygen-containing residual gas, before it is introduced into the ambient air of the fuel cell system. In the gas mixture consisting of the two residual gases, the concentration of the hydrogen is monitored for the exceeding of a limit value. The limit value may then for example be chosen according to the lower ignition limit, optionally with an additional safety distance. If the predefined limit value is exceeded, the hydrogen supply to the fuel cell system can be interrupted. Alternatively, or as a first step, the proportion of the oxygencontaining residual gas in the gas mixture can be increased, by the air or oxygen supply to the fuel cell system being increased for example.
It is an object of the present invention to substantially overcome or at least amerliorate one or more disadvantages of the prior art, or at least provide a useful alternative.
There is disclosed a fuel cell system in which the reactants hydrogen and oxygen circulate in separately regulated gas circuits, of tailoring the regulation of the residual gas output to the boundary conditions within a closed air-independent installation, as represented by a submarine during submerged travel for example.
In a first aspect, the present invention provides a fuel cell system for operation in an airindependent installation, with a number of fuel cells which, for supply with the reactants hydrogen and oxygen, are connected into two separate gas circuits, in which the reactants circulate independently of one another, driven by pumps, wherein the reactants can be introduced into the relevant gas circuit via supply valves and discharged therefrom via discharge valves into the air-independent installation, and with a regulation device which carries out control actions on the supply valves, the discharge valves and the pumps as a function of measured concentrations of the reactants in the gas circuits, characterized in that sensors for

2017242515 12 Jun2019 measuring the concentrations of the two reactants in the air-independent installation are connected to the regulation device, and that the regulation device is configured to modify the control actions on the discharge valves as a function of measured values of the sensors, in order to reduce the discharge quantities of one of the two reactants if its concentration in the airindependent installation exceeds a predetermined upper limit, or to reduce the discharge quantities of both reactants if their concentrations in the air-independent installation exceed predetermined upper limits.
In a second aspect, the present invention provides a method for the operation of a fuel cell system in an air-independent installation, wherein a number of fuel cells are supplied with reactants hydrogen and oxygen in two separate gas circuits, in which the reactants circulate independently of one another, driven by pumps, wherein the reactants are introduced into the gas circuits via supply valves and are discharged therefrom via discharge valves into the airindependent installation, and wherein control actions are carried out on the supply valves, the discharge valves and the pumps by means of a regulation device as a function of measured concentrations of the reactants in the gas circuits, wherein the concentrations of the reactants are measured in the air-independent installation and the control actions on the discharge valves are modified as a function of the measured concentrations of the reactants in the air-independent installation, in order to reduce the discharge quantity of one of the reactants, if its concentration in the air-independent installation exceeds a predetermined upper limit, or to reduce the discharge quantities of the reactants if their concentrations in the air-independent installation exceed predetermined upper limits.

A direct modification of the control actions on the discharge valves is represented by the control variable delimitation, for example. It is also possible, however, to modify the control actions on the discharge valves by changing the target values or limit values for the gas concentrations of the reactants in the gas circuits.
Advantageously, in addition to the concentrations of the two reactants, the pressure in the air-independent installation is also measured, wherein by way of the control actions on the discharge valves, together with the reduction of the discharge quantity of the one reactant, the discharge quantity of the other reactant is increased if the concentration thereof in the air-independent installation exceeds the threshold value predetermined for it and the measured pressure falls below a predetermined limit value. As a result, the reactant, the concentration of which in the air-independent installation exceeds the upper limit, is further diluted or the gas quantity of the two reactants, which can react in a catalytic recombinator arranged in the air-independent installation, increases .
If the oxygen concentration measured in the air-independent installation falls below a predetermined lower limit, the discharge quantity of the oxygen-containing residual gas is increased. If this measure is not sufficient and the oxygen concentration lies below the predetermined upper limit, then in addition the discharge quantity of the oxygen-containing residual gas can be reduced. The reduction of the oxygencontaining residual gas likewise reduces the reacting gas quantity of the two reactants and thus likewise increases the oxygen concentration.

To further explain the invention, reference is made below to the figures in the drawing; each show in detail in a schematic representation :
Fig. 1 an exemplary embodiment of the fuel cell system according to the invention and
Fig. 2 an example of the residual gas output as a function of the gas concentrations measured in the air-independent surroundings, and the ambient pressure.
Fig. 1 shows a schematic representation of a fuel cell system 1 in an air-independent installation 2. The fuel cell system 1 has a fuel cell or one or more stacks of fuel cells 3, which are supplied with the reactants hydrogen H2 and oxygen 02 from pressure vessels 4, 5 and via controllable supply valves 6, 7. The fuel cells 3 are connected into two separate gas circuits
8, 9, in which the reactants H2, 02 circulate independently of one another, driven by controllable pumps (compressors, fans etc.) 10, 11. In the fuel cells 3, some of the reactants H2, are converted into water, wherein the non-converted portions are fed to the fuel cells 3 once more, optionally together with fresh reactants H2, 02.
Due to this circulating operation of the reactants H2, 02, their proportion of inert gas, which is initially very low, increases over time, which corresponds with a decrease in the concentrations of the reactants H2, 02 in the gas circuits 8,
9. The concentrations of the reactants H2, 02 in the gas circuits 8, 9 are measured using gas sensors 12, 13. In addition, the pressures and optionally the temperatures in the gas circuits 8, 9, and also the fuel cell voltages, can be
PCT/EP2017/057429 / 2016P06345WO measured, which is not shown here. The discharge of the reactants H2, 02 takes place via discharge valves 14, 15 as a function of the measured concentration. To this end, the discharge valves 14, 15 and furthermore also the supply valves 6, 7 and the pumps 10, 11 are actuated by a regulation device
16, which obtains measured values delivered by the gas sensors 12, 13. For example, as described in WO2015024785 (Al), in each of the two gas circuits 8, 9 the circulation rate is firstly increased as the concentration of the respective reactant H2, 02 decreases. If, ultimately, a minimum concentration of the respective reactant, e.g. H2, is not reached, then some of the reactant H2 is discharged from the gas circuit 10 in question as a residual gas, and replaced by fresh reactant H2 from the pressure reservoir 4.
Connected to the regulation device 16 in addition are sensors
17, 18, 19, which measure the hydrogen concentration cH2z the oxygen concentration c02 and also the ambient pressure p in the air-independent installation 2.
A catalytic recombinator 20 arranged in the air-independent installation 2 converts hydrogen contained in the ambient air into water vapor in a flameless manner.
Fig. 2 shows, by way of example, how the control actions on the supply valves 14, 15 are modified as a function of the measured values of the sensors 17, 18, 19. In this context, the output quantity of the hydrogen-containing and/or the oxygen-containing residual gas is reduced if the hydrogen concentration cH2 or the oxygen concentration c02 in the airindependent installation 2 exceeds a predefined upper limit OG-cH2 or 0G-C02. If the pressure p falls below a predetermined limit value OG-p and only the concentration of one of the two
PCT/EP2017/057429 / 2016P06345WO reactants, e.g. hydrogen, exceeds the upper limit OG-cH2z the discharge of the respective other reactant, in this case oxygen, is increased so that the hydrogen concentration in the ambient air is diluted. In the case of an oxygen excess, by increasing the discharge of the oxygen-containing residual gas into the installation 2, the quantity of hydrogen and oxygen reacting in the recombinator 20 is increased. Ultimately, the discharge quantity of the oxygen-containing residual gas is increased if the oxygen concentration c02 in the airindependent installation 2 falls below a predetermined lower limit UG-c02. If this measure is not sufficient, then in addition the discharge quantity of the oxygen-containing residual gas can be reduced. The aim of all these measures is that little oxygen (cH2 < OG-cH2) and enough oxygen (UG-c02 < c02 < 0G-C02) are present in the air-independent installation 2, with sufficient pressure (UG-p < p < OG-p). In the remaining cases, the control actions on the discharge valves 14, 15 remain unaffected (no measures), or the residual gas quantities are reduced or increased if the pressure p exceeds the limit value OG-p or falls below a lower limit value UG-p.
