Hydrogen energy systems

There are several different types of fuel cells; proton exchange membrane (PEMFC), alkaline (AFC), direct methanol (DMFC), phosphoric acid (PAFC), molten carbonate (MCFC), & solid oxide (SOFC). Although, some of the these types are already in use, the PEM is one of the most promising fuel cells for widespread use. The problem up to this point has been the high cost of manufacturing hydrogen fuel cells due to the expensive materials used to make them. We believe that we have solved this problem by using substitute materials that are just as effective but at a fraction of the cost and are developing residential systems that will be affordable by the "average" homeowner and pay for themselves in several years.

We are planning to offer several different alternative energy systems which will allow you to get off the grid and generate your own electricity. These systems will burn no fossil fuels, generate no pollution, and are renewable. Although these systems will generate power using different methods, they will all store it utilizing lithium ion cell modules. The system (shown below) stores compressed hydrogen in a tank. Our improvement to this utilizes a hydrogen (from water) generator and the electricity is stored in cells. Since the byproduct of a hydrogen fuel cell is water, this can be a closed system in which the water is re-circulated to start the process over again. The pictures below are just to give you an idea of what the hydrogen system may look like.

Panasonic Corp. has developed a 1.5 kWh battery module from 18650 type  (18 mm in diameter x 65 mm in length) lithium-ion battery cells, which are widely used in laptop computers, to provide energy storage solutions for a wide range of environmentally friendly energy technologies. For example, multiple units can be connected in series and/or parallel to store energy generated by home-use photovoltaic (PV) systems and fuel cells, and power electric vehicles (EV).

Amid rising environmental concerns such as CO2 emissions, great expectations are placed on widespread use of renewable energy technologies such as and commercialization of electric vehicles to alleviate the concerns. However, these technologies require storage systems to become commonplace in daily life. Among a number of technologies, storage systems using lithium-ion batteries in particular are considered promising and practical, because such systems are lighter and have greater capacity than those using other types of rechargeable batteries.

As applications of the storage systems using lithium-ion batteries increase, there will arise demand for such systems with higher capacity, output, reliability and safety as well as improved cost performance. Flexibility in voltage and capacity will also be required according to the application.

Panasonic's compact and high-energy module meets such demands. The module having a volume of approximately 7 L and weighing 8 kg has a voltage of 25.2 V and a capacity of 58 Ah. By connecting a plurality of this module, users can construct battery packs for a variety of applications such as home storage and electric vehicles.

The high-energy module is constructed from 140 pieces of 18650-type cells - seven serially connected rows with each row made of 20 parallel connected battery cells. This structure allows for avoiding serious loss in the system performance such as system shutdown even if some individual cells fail.

Panasonic has a proven record in the production of the 18650-type lithium-ion batteries which are highly reliable and safe, and offer good cost performance. The company has already developed and commercialized a 18650-type lithium-ion battery which has the industry's highest level of capacity.

To achieve the innovative module, Panasonic employed a high-capacity and high-durability cell technology using its proprietary nickel-based positive electrode material. Other technologies used include its cell safety technology that uses a heat-resistant insulating layer between the positive and negative electrodes to prevent short circuits and thermal runaway (overheating) which can be caused when foreign particles get mixed into the battery cell. The new module also uses Panasonic's design technology to ensure reliability by minimizing the effects on power supply if a trouble occurs in some of the cells contained in the module.
