1 00:00:01,430 --> 00:00:08,150 Welcome to the situation in this lecture, we will discuss about fuel cell hybrids work, what are the 2 00:00:08,150 --> 00:00:11,450 advantage, benefits and limitations of fuel cell. 3 00:00:12,650 --> 00:00:17,120 So let's discuss how Will can be used in electric vehicle. 4 00:00:20,060 --> 00:00:27,560 Fuel cell is a device that converts chemical energy of fuel and oxidizing agent into the electricity 5 00:00:27,740 --> 00:00:28,670 like a battery. 6 00:00:29,450 --> 00:00:37,310 Hydrogen is appropriate as a fuel for fuel cell as it produced the water H2O as a byproduct which is 7 00:00:37,310 --> 00:00:41,420 safer for the environment, which compared to conventional CO2 emission. 8 00:00:42,680 --> 00:00:49,730 Otherwise, hydrocarbons like methane, natural gas, ethanol, etc., can also be used as a fuel in 9 00:00:49,730 --> 00:00:50,480 the fuel cell. 10 00:00:52,240 --> 00:00:58,390 And oxygen is used as a oxidizing agent in the process. 11 00:00:59,940 --> 00:01:06,430 And mattress batteries, fuel sell needs, continuous supply of hydrogen and oxygen to produce electricity. 12 00:01:06,810 --> 00:01:10,230 That's how it's different than the conventional battery. 13 00:01:11,760 --> 00:01:13,890 The fuel cell is not a new device. 14 00:01:14,130 --> 00:01:22,350 In fact, the first fuel cells were developed in 1838 by Sir William Group, which is even before the 15 00:01:22,350 --> 00:01:27,650 development of waterlilies, a battery that was developed in 1859. 16 00:01:28,590 --> 00:01:37,050 But the first commercial use of hydrogen fuel cells comes almost a century later in 1932, which were 17 00:01:37,050 --> 00:01:41,700 developed by Francis Thomas Makone, also known as the Back Unseld. 18 00:01:44,890 --> 00:01:51,310 So without going deep into the chemistry of FuelCell, let's discuss more about its pros and cons for 19 00:01:51,310 --> 00:01:52,150 electric vehicles. 20 00:01:52,150 --> 00:01:58,480 System compared the fuel cell with conventional engine midwicket. 21 00:01:59,680 --> 00:02:04,990 Not that same fuel can be used with both fuel cell and I see energy. 22 00:02:05,350 --> 00:02:13,900 But efficiency of fuel cell is 40 to 60 percent, which is two to three times higher than that of CNG. 23 00:02:14,680 --> 00:02:22,090 This is the main benefit of fuel cell, our CNG if we compare fuel cell with the battery. 24 00:02:22,780 --> 00:02:30,910 We know that battery takes much time to charge, whereas fuel cell gives benefit of repealing super 25 00:02:30,910 --> 00:02:35,260 fast as like any other CNG vehicles available in the market today. 26 00:02:36,190 --> 00:02:36,670 So. 27 00:02:41,130 --> 00:02:48,810 What is the problem with FuelCell after having such benefits, our both, I think, and Bedri, let's 28 00:02:48,810 --> 00:02:52,050 discuss about limitations of FuelCell. 29 00:02:54,660 --> 00:03:03,480 Main thing is the energy density of hydrogen, which is very low, that demands higher volume and higher 30 00:03:03,880 --> 00:03:04,390 out fuel. 31 00:03:05,560 --> 00:03:13,180 Thus, despite of higher specific energy, hydrogen needs larger and bulky fuel tank. 32 00:03:14,290 --> 00:03:17,020 The other commercial aspect is Supply-Chain. 33 00:03:17,710 --> 00:03:25,450 Because of lower market acceptance, availability of both the station and supplier of hydrogen is the 34 00:03:25,450 --> 00:03:25,860 issue. 35 00:03:29,000 --> 00:03:36,470 So if you are interested in knowing more about FuelCell Vehicle yet, it's a small task for you, search 36 00:03:36,470 --> 00:03:44,000 for the latest and as well as past hydrogen based vehicle and started their performance and customer 37 00:03:44,000 --> 00:03:44,430 review. 38 00:03:44,660 --> 00:03:51,290 And don't forget to share the same in the comments section or the or discussion and knowledge. 39 00:03:56,060 --> 00:03:57,440 So if we summarize. 40 00:03:58,290 --> 00:04:02,040 Commercial use of hydrogen as a fuel, then we can see. 41 00:04:03,420 --> 00:04:11,760 First, we started using hydrogen in icy engine with the vehicle, then we realized that we can have 42 00:04:11,760 --> 00:04:19,380 higher efficiency with the fuel cell as well as we will get all the benefits of electric motor, our 43 00:04:19,380 --> 00:04:20,220 icy engine. 44 00:04:21,030 --> 00:04:23,880 What size and weight of fuel cell is the. 45 00:04:27,960 --> 00:04:37,170 This trend is to use both military as well as fuel cell run, electric car or vehicle, this way we 46 00:04:37,170 --> 00:04:38,690 can solve three problems. 47 00:04:39,390 --> 00:04:42,790 The first, we can have a good vehicle range. 48 00:04:43,380 --> 00:04:53,040 The second is we can have limited size of fuel tank as we have battery to and we can fill it quickly 49 00:04:53,250 --> 00:04:56,340 and get rid of spending hours of charging the vehicle. 50 00:04:59,370 --> 00:05:07,650 Here is the latest fuel cell vehicle from the unit that I captured during the Auto Expo 2020 held at 51 00:05:07,650 --> 00:05:08,760 Noida, India. 52 00:05:12,100 --> 00:05:18,900 But it's not still enough from the commercial point of view, adding fuel cell to battery increased 53 00:05:18,940 --> 00:05:23,280 the initial cost and problem of supply change of hydrogen remains there. 54 00:05:24,090 --> 00:05:31,960 Thus, if we can reduce the charging time of battery at some acceptable level, then that is nothing 55 00:05:32,230 --> 00:05:35,210 more better than your battery electric vehicle. 56 00:05:35,830 --> 00:05:44,110 However, use of other energy sources like ultra capacitor and flywheel, along with the battery, may 57 00:05:44,110 --> 00:05:47,290 help extending battery performance and vehicle range. 58 00:05:48,410 --> 00:05:56,810 So hope you got the idea about FuelCell and its association with the electric vehicle and see you in 59 00:05:56,810 --> 00:05:57,650 the next lecture. 60 00:05:57,830 --> 00:05:58,310 Thank you.
