Algae fuel cell cranks up efficiency by five times

The researchers at the University of Cambridge have developed a new algae-based fuel cell, which shows five-fold greater energy efficiency compared to its previous version as it traps sunlight and turns it into electricity like a synthetic photovoltaic.

The novel technology, called biophotovoltaic, uses genetically-modified algae cells engineered to check non-productive release of electric charge, writes Tree Hugger.

Unlike the earlier versions, the new fuel cells have two separate chambers for two core processes – charging and power delivery – an approach that serves the conflicting requirements of both the processes without affecting the power output, notes New Atlas.
