Fuel cells power generation system
First Claim
1. A fuel cells power generation system, comprising:
- fuel cells that receive a supply of a fuel and generate electric power;
a hot water tank that stores hot water heated with at least heat from said fuel cells; and
an operation display module having an operation unit that is manipulated to control operations of said fuel cells and a display unit that displays an output electric power from said fuel cells and a hot water storage state in said hot water tank.

Abstract
The power generation mode of fuel cells included in a fuel cells power generation system, the quantity of power generation by the fuel cells, the working power used for a load, the amount of hot water kept in a hot water tank, the time, the occurrence of an abnormality in the system, and a request for regular inspection are displayed on a display unit of an operation display panel as numerical values and stepwise-variable graphical expression representing variations in quantity. The user is accordingly informed of the current driving conditions of the system and the working power used for the load, and sets the power generation mode of the fuel cells based on these pieces of information. This enables the user to adequately and readily control the operations of the system.
