A Type 212 submarine of the German Navy, equipped with a fuel-cell AIP. A diagram of the fuel-cell AIP module developed by the DRDO of India. Siemens has developed a 30–50 kilowatt fuel cell unit, a device that converts the chemical energy from a fuel and oxidiser into electricity. Fuel cells differ from batteries in that they require a ...
A Bioelectrochemical reactor is a type of bioreactor where bioelectrochemical processes are used to degrade/produce organic materials using microorganisms. [1] This bioreactor has two compartments: The anode, where the oxidation reaction takes place; And the cathode, where the reduction occurs.
Subnautica is a 2018 action-adventure survival game developed and published by Unknown Worlds Entertainment. The player controls Ryley Robinson, a survivor of a spaceship crash on an alien oceanic planet, which they are free to explore.
Diagram of a battery with a polymer separator. A separator is a permeable membrane placed between a battery's anode and cathode.The main function of a separator is to keep the two electrodes apart to prevent electrical short circuits while also allowing the transport of ionic charge carriers that are needed to close the circuit during the passage of current in an electrochemical cell.
It produced a power output of about 1 μW at a power density of 10 μW/cm 3. At those values, its energy density would be approximately 3.3 Wh/g over its 100-year half-life, about 10 times that of conventional electrochemical batteries. [6] This research was published in April 2018 in the Diamond and Related Materials journal. [7]
Primary cells are made in a range of standard sizes to power small household appliances such as flashlights and portable radios. [citation needed] As chemical reactions proceed in a primary cell, the battery uses up the chemicals that generate the power; when they are gone, the battery stops producing electricity.

International Space Station solar array wing (Expedition 17 crew, August 2008).An ISS solar panel intersecting Earth's horizon.. The electrical system of the International Space Station is a critical part of the International Space Station (ISS) as it allows the operation of essential life-support systems, safe operation of the station, operation of science equipment, as well as improving crew ...
A thermionic converter consists of a hot electrode, which thermionically emits electrons over a space-charge barrier to a cooler electrode, producing a useful power output. Caesium vapor is used to optimize the electrode work functions and provide an ion supply (by surface ionization) to neutralize the electron space charge. [6]
