Fuel Cell Background
{"Image DocumentName": "Fuel Cell Background", "Image ImageDescription": "In principle, fuel cells can be considered as batteries that convert chemical energy to electricity without combustion, but instead through electrochemical reactions. The difference between fuel cells and conventional batteries is that fuel cells can run continuously as long as fuels are available for electrochemical reactions, whereas a battery needs to be recharged periodically. The concept of fuel cells was conceived by Sir William Robert Grove, known as the father of the fuel cell, who develop a gas voltaic battery in 1839, later named the Grove cell. Accelerated research and engineering for fuel cell development started in the 1960s due to the unique needs for the long-endurance manned space exploration missions. For space applications, in addition to less toxcity, fuel cells have the advantage over traditional batteries, as they offer significantly higher energy density (energy per equivalent unit of weight) than conventional and advanced batteries.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
