Abstract

The present disclosure describes a three-tier hybrid electrochemical power generation system (CHFC-2) and its scaled-up research extension (CHFC-3) that produces low-voltage DC electricity from materials available in domestic, shelter, and post-disaster debris environments. The system combines two power engines in a single cell: (1) a galvanic engine using an aluminum anode and copper cathode in an acidic saline electrolyte, producing 0.5–1.0 V within 1 hour of assembly; and (2) a microbial fuel cell (MFC) engine using soil-inoculated organic substrate, ramping up over 3–14 days and sustaining power for weeks to months with periodic refueling. The CHFC-3 extension introduces a central bio-reactor architecture (one large fermenting reactor with multiple replaceable anode modules sharing a single cathode, producing 1.7× higher power density and 2.2× lower internal resistance than equivalent independent cells), an energy accumulation layer (electrolytic capacitor bank charged in parallel, discharged to the load), and passive thermal regulation via ground burial. Three build tiers are disclosed: Tier 1 (household, 30 min), Tier 2 (shelter, 1 hr), Tier 3 (debris field, 2–4 hr). A 4–8 cell series-parallel stack with capacitor buffer and a 7805 voltage regulator (or dedicated DC-DC boost module for low-voltage stacks) produces a regulated 5 V DC output capable of charging a mobile phone, powering an AM/FM radio, or running a small LED light. All components are sourced from items available in any kitchen, any occupied building, or any post-disaster urban rubble field. No exotic materials, no industrial infrastructure, and no high voltage are required. This is a Conceptual only Research Invention and should be reviewed by professionals in this field only using safety first at all times to follow.
