A home fuel cell is a residential-scaled energy system based on fuel cell technology. Fuel cells are able to fulfill both the electrical and heat demands for a house. The initial cost of a Panasonic home fuel cell is $30,000. A homeowner will finance a system at a finance rate of 10% per year over a three-year period. A down payment of ten percent is required. The operating cost of the fuel cell is expected to be $3,500 in the...
