What does PEM stand for in fuel cells?
Polymer electrolyte membrane (PEM) fuel cells, also called proton exchange membrane fuel cells, use a proton-conducting polymer membrane as the electrolyte.
What is fuel cell CHP?
Fuel cells use an electrochemical process to convert the chemical energy in a fuel to electricity. For stationary power, fuel cells are used for distributed generation (electricity only) and are also configured for combined heat and power (CHP).
How long do PEM fuel cells last?
Economical viability of PEM fuel cell power for stationary applications demands a fuel cell lifetime of at least 5 years, or over 40,000 hours of continuous operation.
Are fuel cells commercially available?
Fuel cell electric vehicles are now available in the United States! Offering completely zero emissions, these passenger vehicles have the driving range, ease of refueling, and performance of today’s gasoline vehicle.
What is the difference between Sofcs and PEM based fuel cells?
Both techniques have comparable electrical efficiency. PEMFC is compact and handles generally load variations better. SOFC is not as compact and works at higher temperatures than PEMFC. The SOFC can be combined with a gas turbine increasing its efficiency.
What catalyst is used in fuel cells?
Palladium in fuelcell catalysis
Carbon supported platinum is commonly used as anode and cathode electrocatalyst in low-temperature fuel cells fuelled with hydrogen or low molecular weight alcohols.
What are the types of fuel cells?
Types of Fuel Cells
- Polymer electrolyte membrane fuel cells.
- Direct methanol fuel cells.
- Alkaline fuel cells.
- Phosphoric acid fuel cells.
- Molten carbonate fuel cells.
- Solid oxide fuel cells.
- Reversible fuel cells.
What is cogen power?
Cogeneration, also known as combined heat and power (CHP), is the simultaneous production of multiple forms of energy from a single fuel source 1. Thermal (heat) and electrical (electricity) are usually the two forms of energy produced in many types of cogeneration applications.
How much does fuel cells cost?
Fuel cell electric vehicles are currently manufactured at low production volume, and are available for sale or lease in the US for approximately $58,300 or $379-$389/month.
Do fuel cells wear out?
But fuel cells do not discharge and degrade over time. Theoretically, the metal hydride should not wear out, though in practical use it could deteriorate.
Who is the leader in fuel cell technology?
FuelCell Energy, Inc.
FuelCell Energy, Inc. is a global leader in the design, manufacture, operation and service of ultra-clean, efficient and reliable fuel cell power plants.
Who is the largest manufacturer of fuel cells?

How many types of fuel cells are there?
Which is the best type of fuel cell?
Alkaline Fuel Cells
Operating at 60-70ºC (140-158ºF), AFCs are among the most efficient type of fuel cells, reaching up to 60% efficiency and up to 87% combined heat and power.
Why is fuel cell so expensive?
Unlike a battery, where most of the cost comes from the raw materials used to make it, the most expensive part of a fuel cell is manufacturing the fuel cell stack itself—not the materials to produce it. The cost to build and maintain hydrogen stations also needs to decrease for the market to support a hydrogen economy.
What chemicals are in fuel cells?
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions.
What is one problem with fuel cell?
Expensive to manufacture due the high cost of catalysts (platinum) Lack of infrastructure to support the distribution of hydrogen. A lot of the currently available fuel cell technology is in the prototype stage and not yet validated. Hydrogen is expensive to produce and not widely available.
What is the most commonly used fuel cell?
The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its inventor, is one of the most developed fuel cell technologies, which NASA has used since the mid-1960s.
Is Cogen renewable?
Cogeneration can run on any renewable fuel and is the most cost-effective way of using renewable fuels. Currently, 27% of fuels used in cogeneration in Europe are renewable, mainly biomass and biogas. Empowered businesses and citizens.
What is DSM energy?
Demand Side Management (DSM) is a strategy used by electricity utilities to control demand by encouraging consumers to modify their level and pattern of electricity usage.
How far can you drive with 1 kg of hydrogen?
The increased efficiency of the fuel cell system, coupled with a 1 kg increase in hydrogen capacity gives the Mirai a certified range of approximately 650 kilometres (400 miles), under normal driving conditions.
How much does 1kg of hydrogen cost?
Fossil-based hydrogen costs about $1.80/kg, and the commission estimated the cost of blue hydrogen, which pairs carbon capture with steam methane reformation of natural gas, at about $2.40/kg.
What is a disadvantage of fuel cells?
Why hydrogen is not the future?
It doesn’t exist on our planet in a pure state, so it has to be extracted from compounds from which it doesn’t really want to be separated, taking a lot of energy.
