High efficiency fuel cells
WebIntroduction. High- temperature fuel cells such as the solid oxide fuel cell (SOFC) is an important type of fuel cell that can be used as an alternative to the conventional heat engine owing to the high efficiency of energy conversion. This type of fuel cell, first invented by Grove (1839) and Schönbein (1838), has undergone a major ... Web27 de mar. de 2024 · Tony Leo. March 27, 2024. Fuel cells are a remarkable source of clean energy that operate at high electrical efficiency and release very few emissions or pollutants into the atmosphere. The low emissions and high efficiency of fuel cells are key to understanding the fuel cell value proposition and sustainability profile.
