Abstract
A power generation device includes a filter holder that is a container filled with water and a filter member. The filter member is composed of porous glass in a form of a plate and arranged in the filter holder between a first space upstream from the filter member and a second space downstream from the filter member. The filter member allows hydrogen ions to pass therethrough more easily than hydroxide ions. The power generation device generates electric power based on a potential difference between the first space and the second space when a water flow from the first space toward the second space is produced in the filter member. The water flow flows along a direction of thickness of the filter member.
