Talking about the use of fuel power battery in the process of chlor-alkali electrolysis

The fuel power cell is fed into the fuel power cell through fuel and air separately, and electricity is peculiarly processed. From the outside, it has positive and negative electrodes and electrolytes, etc., like a battery, but in fact it cannot 'storage' but a 'power plant'. However, it requires electrodes, electrolytes, and redox reactions to generate electricity. The electrochemical processing of Cl2 and NaOH using brine is one of the processes with the highest electricity intensity in the chemical industry. The chlor-alkali industry consumes about 1% of the world's electricity. If the device is not part of an integrated chemical complex (H2 can be used), then H2 is often emitted as a by-product. Theoretically, up to 20% of the electricity required for electrolysis can be supplied by all the H2 processed by the chlor-alkali plant. The Netherlands NedStack and Akzo Nobel Basic Chemicals Co., Ltd. built a joint venture membrane electrolysis unit in Delfzijl, the Netherlands. The unit is equipped with a 50KW proton exchange membrane (PEM) fuel power cell power generation facility downstream project. The project uses H2 by-products from the electrolyzer as feedstock. , The system consists of 12 proton exchange membrane reactors, which are manufactured by NedStack, each with 75PEM fuel power cells. The effective area of u200bu200beach battery is 200cm2. The system generates a peak power of 120MW and a static power of 50KW in use. It has an ideal fuel power cell conversion efficiency at a 56% (low calorific value hydrogen) operating point. As of mid-April 2008, the system has been connected to the grid and has been running for more than 4,000 hours. Fuel power cells generate more than 200MWh. It is said that it will be used in the chlor-alkali industry plan to enlarge the system to 1MW soon. Akzo Nobel also plans to put into operation a 15KW alkaline fuel power cell at the chlor-alkali plant in bitterfeld, Germany. The advantage of the alkaline fuel power cell over the PEM system is its lower cost. In addition, the American Nuvera Fuel Power Cell Company completed the field test of the Forza fuel power cell on the chlorate processing plant of Caffaro Chemical Company in Brescia, Italy. The 120KW facility was set up by Uhdenora. It has generated 185,000 KWh, and the utilization rate exceeds 95%.
