Fuel Cell Technologies
Ryan JernNovember 24, 2008
What is a fuel cell?
HistoryFirst fuel cell created by William R. Grove
1839 in Swansea, Wales
Called it “Gaseous Voltaic Battery”
Firsts tests his creation using two platinum electrodes halfway submerged in sulfuric acid
Each electrode had one tube connected to it, one tube filled with oxygen the other with hydrogen
Gaseous Voltaic Battery
Fuel Cell Introduced to
AmericaIn 2003 State of the Union Address President Bush introduced $1.2 billion Hydrogen Fuel Initiative
Since research and development put fourth to reduce green house gases
Just recently Fuel Cell Technology became a reality
Types of Fuel CellsType Use/Description
Polymer Exchange Membrane Fuel Cell
Popular in automotive vehicles due to its relatively low operating temperature
Solid Oxide Fuel Cells Used for large scale stationary generators due to high operating temperatures; one of longest operating lives among fuel cells
Alkaline Fuel Cells Used by NASA although vulnerable to contamination therefore unlikely to be commercialized
Molten-Carbonate Fuel Cell
Best used for large stationary generators although less expensive than Solid oxide fuel cells due to less of need for exotic materials
Phosphoric-Acid Fuel Cell
Best used for small stationary generators; high operating temperatures and long warm up time make unusable for automobiles.
Direct-Methanol Fuel Cell
Low operating temperature could potentially be used in automobiles although required materials make it to expensive
Fuel Cells TodayNeed two elements
Hydrogen
Oxygen
Both pass through electrode
Meet at electrolyte and react
HEAT & WATER VAPOR
How does fuel cell technology effect
us?
Automakers
Realize the positive economic impact
Offering free lease opportunities
Chevrolet and Honda
Project Driveway
Chevy Equinox Commercial
Efficiency
Study done by Honda
Gasoline Hybrid Fuel Cell
Driving Energy
Efficiency %
20% 30% 60%
What’s holding back production?
DifficultiesThe cost to implement fuel cell technologies is to high in comparison to internal combustion powered vehicles
The availability of hydrogenOver 150,000 gas stations in the US
US Gas Stations
DifficultiesMay not be durable enough
Atmospheric pressure
Strain put on the fuel cellCity traffic; stop and go
RealisticHonda leasing first fuel cell vehicle
Honda FCX Clarity; $600 month
Some public vehicles are Hydrogen powered although will not be readily available for some time
Will fuel cell technology be the solution to our emissions problems?
